Another ZF swap
Well like the title say's, the 4+3 is done irritating me. I had the overdrive working again, and on my way to the races this weekend, it quit. Again! So I got on ebay, and found this.
http://www.ebay.com/itm/Corvette-Zf-6Speed-Transmission-Conversion-/271251574706?_trksid=p2047675.l2557&ssPageName=STRK%3AMEWAX%3AIT&nma=true&si=F3CGLbWuBLx1asDKWkyqT%252FZmDAg%253D&orig_cvip=true&rt=nc
So I gave him a call, and I am mailing him a check in the morning. (His idea) Now I know the clutch, and pressure plate wont work. So I am looking for some of your guys experience in some of the parts you're using. Ie. TOB, FW, Clutch. Looking for best working, as well as ease of operation. Also, is the pilot bearing the same? And, what have others done about shifter location. Thanks for the input. h

Easiest way is to cut out the 4+3 shifter box and glass in the tunnel section from a ZF car

Do you know if anybody makes a tunnel piece in the aftermarket? h

You'll have to fabricate the tunnel piece but it far from hard. Here's the link to one of the T56 conversion threads. My self and 87Bob took some nice pictures of the 4+3 "hump" area removed and then re-glassed.

Thanks Dan. Whats your opinion on the Fidanza flywheel vs the long pivot ball? I really want to do it right, and the extended ball seems a bit hokey. Im old, so for the most part I drive pretty normal, (quite a bit of drag experience, and looking to do some autox) but when I do get on it, I expect everything too work beyond my expectations.
Also can you tell me about shifter position? I mean, will I have to do any fab to the console itself? Thanks for the help. h

Thanks Dan. I guess I should have checked the link before asking questions! Lol. Still no real location of a zf shifter. I did find measurements of a zf compared to a t56, and its to the left about 1 1/4in farther than the t56 so I wonder if I can just weld a 3/4in spacer in there. I guess I have to wait for it to arrive, before I start speculating.
Back to the flywheel. Does anyone make a dual mass for the older engines? The guy is sending me the one that was with the tranny, that has been resurfaced, but from what I'm reading that won't work. Why won't it work? Can it be made to work?
Sorry for all the questions, just trying to get my ducks in a row, so it goes as smooth as possible. h

You should attempt to find an M6 car in a "local" salvage yard and check the floor pan "first hand"! If it's been seriously parted it could be a very inexpensive "local" buy.
If your interested in just some snapshots post a request for maybe someone that is doing carpet, sound dampening or interior swap in an M6 car. There should be many. There might e several You-tube videos of sound dampening installs, or interior swaps. I would think the visuals should be easy in a "google image" search - I'd think!

I'd be a little leery of the DMF being resurfaced. Make sure you check that thing out really good. Make sure it doesn't rotate by hand and it doesn't look like any black goo came out.

I did the ZF swap in 2003 in my 85. At that time Fidanza made an aluminum flywheel for this conversion, 2 pc rear main and the ZF, it has worked well for me. I am not sure they still offer this part though. If not I recall reading at the time some people had success with the stock 85 flywheel and short pivot etc, maybe something to check into. There use to be more threads on this conversion not too many lately. I will look for the Fidanza flywheel part number and post if I can find it.
Shifter position is the same as the 4+3 so no issues with that. I put on a Hurst short throw shifter and I do not have any interference issuers with the console shifter opening, some have used the 89 console but even back when I did my swap those were almost impossible to find.
Good luck,
Brian

The reason for my q's, are because right now my 4+3 is making a horrible rattling noise, and has since I bought it. (Fluid change made it a tad quieter) So I was trying to get away from a noisy trans, and was hoping that somebody had come up with a dual mass FW for older motors. h
