(12-29-2013, 11:29 AM)raysorenson Just making sure because it was my assumption that you had seen my posts regarding my correspondence with revshift discussing whether or not any of their existing discs would fit the W124. When you said the M3 discs looked like a fit, I also assumed you knew something I didn't. I'd rather not open my mouth at every opportunity to repeat myself, but it looks like I should have done so in this case.
After sending them a drawing with comprehensive and precise measurements, I was told that the '05-06 GTO flex discs were an exact match. If you'd like, I can forward my correspondence with revshift, complete with .pdf's so you can verify my measurements. PM me with your email address if you're interested.
With luck, the GTO rebuild kit will fit into your BMW flex disc.
OK there seem to be a few options for the early w124 cars. They all had small diameter flex discs and limited clearance at the transmission mount, so it is not as simple as bolting in the 8-hole V8 guibos and a v8 driveshaft. Options are:
1. buy an '05 GTO flex disc for the front, and the stock driveshaft. Supposedly per surfrodder this fits the stock transmission output spider. I guess this should also work in the rear location, but anyone upgrading to a 210mm 500SL diff or equivalent will need to pull the spider off the old differential and install it on the new one to match the old driveshaft. This seems a bit silly for high HP, as the center bearing on the old driveshaft is smaller than the V8 version, but whatever. I also wonder if those small diameter GTO flex discs will hold up, even though a GTO had a lot of torque and power and was pretty high performance.
2. Use gwagen output flanges and a gwagen driveshaft, altered to suit the car; not sure where to get a part number for the gwagen driveshaft but I'm sure the part number is available somewhere.
3. Use the spicer yokes front and back with either a single piece driveshaft (seems like it would interfere with exhaust in the tunnel) or a custom one like SurfRodder showed above, with the stock center bearing mount. Supposedly the v8 center bearing mount will fit into the early cars.
4. Swap to a 722.6 transmission, which must have more clearance at the transmission mount than the early w124 722.3 does. Then a v8 driveshaft and stock 8 hole guibos front and back.
