Yeah best thing ever

No I did not know that was a thing

Well I just nipped off that corner problem solved. I used energy suspension bushings, seemed fine. 10 Mile Test Drive then back on the lift for torque check, No issues no noises not even spraining oil out the vent, yet. 1 million thanks to all of you for your sage advice. Ended up spending about 250 for the R 200 bar, bushings technoversion‘s front mount gasket oil, not too bad.

install done, all good, it seems, have a clearance issue and then drop and drive, I'm thinking of hacking the corner off the diff case to clear the exhaust, not an issue?

I've looked long but am still foggy, sorry, I assume that when installing the R200 in a 240 you need to install the mustache bar as it is in the 280, that is with the bar coming off the backside of the bushing mounts and running behind the suspension uprights, as in the the top picture NOT the R180 mounting which is bottom pic? So I get to take the whole rear end out (or at least a healthy chunk of it) I found this guy and was able to put the top plate, top half of bushing onto the bolt (stuck with grease to hold it up there) and push the bushing's tube back down a ways, then I could sneak the bar on without taking other pieces off, well I did undo the sway bar, I should be able to reassemble the bushings with the bar in place

I'll probably take it off as I'm putting on the Technoversions upper mount in lieu of the strap, can't see this doing much besides adding a lot of dead weight

I thought it was some hack job by a previous owner until I saw the same thing on this picture: Why?

okay thanks, I've since found this: I will just use my 240 shafts and see how it goes. mustache bar bushings are out of stock a lot of places, got a set coming via amazon but have to wait.....

I'm in the middle of swapping in an R200 to a '72 240. i've read conflicting info on needing the 280z's half shafts, the R200 is wider by a bit and offset more left so I'd "think" you'd need a shorter half shaft/axle (Datsun calls them driveshafts) on the left for sure. Can't really confirm this in research, surprisingly but if I need to hunt down half shafts I'd better start.

back home with the Florida R200, it looks like the pinion shaft flange will work, I'm waiting on the Technoversions mount and wondering about the mustache bar bushings, should be replaced I think, source? I'm still foggy on the half shafts, I think I do need those off a 280 don't I? the R200 is about and inch wider than the R180 so don't I need shorter half shafts? and a rear cover gasket, should get that.......

The old one was constantly blowing oil as in dripping spots ground if it sat a while

Old 180 would blow a lot of oil out the vent, should I consider tapping the vent hole to add a fitting and hose ……?

I can’t just bolt my existing axle shafts to those?

Scheduled to pick this one up tomorrow I think it’s an R200. I hope so. Looks like the right shape on the rear and it doesn’t have a stub axle bolts. technoversion mount ordered too

Thanks for the tip I got two leads on R200s at the moment both with bars there’s one down in Florida for 120 bucks right where I’m going to pick up U-Haul truck for other reasons in two days that might work out quite nicely

All right great I will work on getting that one then but just to double check I shouldn’t need his half shafts, mine should work right? I will get them if available as far as the driveshaft flange goes if I got a swap them around it’s doable

My half shafts won’t bolt to that? He said he’d take more pics this morning but sure looks like a R200 to me from here

I wonder if I could this dude in there: https://www.facebook.com/marketplace/item/681612189273877?ref=search&referral_code=marketplace_search&referral_story_type=post&tracking=browse_serp%3A81fcf3e1-4bba-4d96-8fae-fd4b8cd5059d otherwise I may have found a R200 with the bar still on it, bit of a road trip but doable you can see it on the back of the trailer https://www.facebook.com/marketplace/item/452932285817588/?referralSurface=messenger_lightspeed_banner&referralCode=messenger_banner

I'd rather just buy the right one if I can find one for okay $$, if not, I can weld and drill.

yep! kinda fun

alright ,we're getting somewhere, 2) I may have to buy the ebay one mentioned then (or can you weld a plate over the old holes and redrill?) 3) yes, I removed the diff with front mount still on it 4) the driveshaft is custom of course, since it's a 350 but I can get that modified if needed

okay the busted R180 was a 3.54 as well, I think as per this picture of ring gear numbers: this car was assembled in 1995 and it lasted that long, with lots of drag racing slips (from PO) to prove it was beaten on, so that's one that went for a while anyway, it doesn't look like it was swapped before, at least to my eye

okay, gotta get my terms straight; the "rear transverse link mount" on our '72 is already curved, is this sufficient? (top pic) and the differential case mounting bar (aka "mustache bar", you called it "diff mount" above?) (middle pic) needs to be replaced? As per the ebay link above? Is that the best way to go for one of those? and I think I agree, the technoversions diff mount (front) is a good idea. Last pic for overall reference

there's a R200 available in Cincinnati, https://www.facebook.com/marketplace/item/453259465957942/?referralSurface=messenger_lightspeed_banner&referralCode=messenger_banner which I'll be driving past this weekend, I could snag that and then source the other bits (mustache bar here? https://www.ebay.com/itm/223539776365?fits=Model%3A240Z&hash=item340c024b6d:g:EpAAAOSw76hZjaqt or better source? Then I still need a few more bits. I could just pop another R180 in there too I guess.......

looking for R200 to replace the R180 I recently trashed. Still learning but the move to the R200 involves mustache bar and front mount I believe, would like to source all at once if possible, LSD or not, whatever, it's just a weekend toy so not too worried about it, might just put another R180 in there, last one lasted 25 years so can do again, so any working diff considered, looking to spend from $200 to $1000.
