I also did a cowl mod, but left the pass side vent hole open.
I use glass cloth (4 layers), then fill & sand, fill & sand . . . . . . .
Ck it out, click Z pics in my sig.
The average user has no clue what someone with some knowledge can do with an unsecure wireless connection.
Wireless is great technology, but beware what the salesperson doesn`t tell you (or know them self).
Find some tech folks and ask lots of ?`s.
Don`t know about a kit ???
Try a search.
Hybridz member "Mark" is one that I know has done this swap.
Search for his posts and you will find his info.
He also has some pics in his personal gallery.
There also are other members that have developed "kits" for our cars.
Search for Mike Gibson (aka) SCCA and Ross (Modern Motorsports).
There are others also, sorry I missed some of them.
John,
I the 79 - 81 ZX masters will bolt up with no mods.
The 82 - 83 mounting is different.
I used the earlyer ZX 15/16 master on my Z.
I also changed frt calipers and installed a tilton pro valve all at the same time.
All I can tell you is do it, it is an inprovement over the stock Z master.
41 as of this past October.
I`ve owned my Z since 1981, that`s half my life.
You younger folks, Don`t let time slip away.
The years go by quicker every year.
I use them on a track car and change them after 2 years.
I have worn out rear ajustable bushing but the frt have done well.
How you use you car would make some difference.
If you already have them in, leave them and take advantage of the ajustability.
No need to just replace them.
