Bud, I've used LuK, Exedy and Sachs. All are pretty much the same...the Sachs impressed me as being better made than others and the cost was okay. Last time I had to hunt because I was swapping the transmission for a T5 (different spline count) and also I have an 11 inch flywheel. If you take your time and search, you can find one that will work even if you have to mix/match. As I recall I used a Sachs pressure plate designed for the 11 inch Chevy 235 flywheel (as you said the "many fingers" type) and a LuK disc designed for one of the early Astro Vans (11 inch clutch w/14 spline count). I got both from Rock Auto along with a shortie throwout bearing. Everything mated just fine but I had to make a new connecting rod because the original was too short...or too long. Sorry, can't remember now but with the 11 inch plate it is very smooth.
