Guest Anonymous Posted January 23, 2002 Share Posted January 23, 2002 you may have seen my post on making JTR motor mounts with the aid of a transfer punch. A transfer punch has the same diameter of the hole you wish to drill. For example,your template is a gasket for a fuel pump that you want to make a block off plate for. You place the template on the fuel pump block off metal stock and align your same diameter transfer punch to the gasket hole and punch with a hammer onto the metal stock of your future block off plate or you want to make the three holes on your JTR motor mount plate using the GM motor mount. Select the same diameter transfer punch as the GM motor mount holes and align the GM mount to the JTR plate; center the transfer punch to the GM mounting hole and hammer with a punch onto the JTR plate .A picture could be worth a 1000 words in this excersize .A Harbour Freight outlet would be a good source for a set of inexpensive transfer punchs Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted January 23, 2002 Share Posted January 23, 2002 depends on what year the car is. mine is a 73 240 (obviously) and there is not enough material to drill to a five pattern. in other words...if the flange is not round there won't be enough room for five lugs. my flange is kinda sqaure with the 4 lug studs positioned near each corner. Hope this helps. I believe that SCCA made the punch you are referring to. Quote Link to comment Share on other sites More sharing options...
Guest scca Posted January 23, 2002 Share Posted January 23, 2002 there is enough meat on the rear hub to drill to 5 lug.. i use a rotor as the template and make a punch to fit into the rotor holes for transfer .. to date teh best write up on doing this is with BLKMGK.com or on alsils page.. they both have lots of info on how to do it yourself (labor wise) once you have the right pieces Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted January 23, 2002 Share Posted January 23, 2002 For the do it your selfers out there you can buy a transfer punch set from Eastwood for about 25 bucks. It comes with about 15 different sizes. Quote Link to comment Share on other sites More sharing options...
Dan Juday Posted January 23, 2002 Share Posted January 23, 2002 The problem I see with using a Ford brake drum for a template is that the hole in the center must be a tight fit on the (don't know what it's called, protrution?) on the hub. Off by a little and you've got trouble. Mike/scca, if a guy wanted to re-drill his hubs but stay with the drums, do you sell a template or does he have to pay for a rotor that he will not use? Don't mean to sound like I'm complaining. I'm looking at going to 5 lug too and the budget is getting tight. "Sweat the pennies and the dollars will take care of themselves".

Danno74Z Posted January 24, 2002 Share Posted January 24, 2002 Dan, I went to a wreaking yard that specializes in foreign cars and picked-up a "junk" 300zx rear 5-lug rotor. Most yards have 55-gallon barrels filled with scrap rotors that don't meet the minimum standard for turning. They may even give you one. You can use that rotor as a template to redrill your drums. When you’re done with the used rotor you can give it back to the salvage yard for recycling. Danno74Z Quote Link to comment Share on other sites More sharing options...
Guest scca Posted January 25, 2002 Share Posted January 25, 2002 get the transfer kit - and a used rotor thats the cheap way out ---- if u'r watching pennies/// OMG drums under 5 lug? the transfer punch set should be close to the rotor flange hole diam. i make a punch to fit the new rotor holes. no room for a mistake there... a 1mm off and it WILL wobble Quote Link to comment Share on other sites More sharing options...
Guest scca Posted January 27, 2002 Share Posted January 27, 2002 i guess what i dont understand is IF you are converting the rear to disks why you dont just pony up and buy new rotors and use THAT as the template? seems to be your making it far more difficult than it need be. the rotor you use will be the template so no need for a scrap rotor for this purpose Quote Link to comment Share on other sites More sharing options...
Dan Juday Posted January 27, 2002 Share Posted January 27, 2002 Well Mike, the reason for me is priorities. I don't plan on upgrading my brakes at this time. I need a larger selection of affordable wheels, especially with the wide fenders I've got. The selection of 8 1/2 and 10 inch wide rims jumps way up going to 5 lug. I hope to upgrade the brakes in the future sometime. But for now there are just too many other areas of the car that need my money before it will be roadworthy.

Guest scca Posted January 29, 2002 Share Posted January 29, 2002 if you want to use a one piece rotor with the maxima brackets i sell one that will fit under that with 82 zx calipers for $50 ea brembo brand. this is NOT the Z31 rotor.......the Z31 or Z32 is too large OD to use the maxima bracket. BTW i have ONE set of maxima brackets left new in box $150 includes shipping!, new in wrappers. we also have the caliper brackets done now that will bolt up with the Z31 rotor and the 240sx calipers..this is the larger 11.3" OD rotor. if you want vented use the Z32 rotor and make weld on brackets, bolt on is impossible virtually.

Guest scca Posted January 29, 2002 Share Posted January 29, 2002 AFAIK i was the first one to use Z32 rear brakes on a early car. this is "easy" in a way as you use all the Z32 stuff but NO FRICKIN ebrake!!!!!!!!!!!!!!!!!!! you must weld ONTO the carrier area of the rear bearing area to mount the calipers... the offset on the Z32 rotor comes so far back it covers the mount flange that you would use for the bracket- thus any way to bolt this on is lost. others here have thought that the ebrake would fit only to discover that NO it would not fit. if you really want to re-engineer the rear suspension maybe but otherwise nope..the inner drum for the ebrake must come back to fit and there is not enough room for this to work. my convertible has the Z32 TT rears but no ebrake except for the hydraulic park lock - works ok but i wouldnt rely on it for daily use. my car is a summer car only and i generally dont park it out of my site and not on a hill.
