You can get a disc made up at a clutch shop or there is a place listed in the tech tips in Springfield, Mo. that makes them. You can use one for an Astro van or Camero but they just sell complete kits anymore. They say money can't buy happiness. It can buy old Chevy trucks though.

Also have run an RCF-4201. These are 9-7/8" discs. They both will have the proper spline count and neither had to be modified. These are for an S10 T5...the Camaro uses a different input shaft with a different spline count.
Just be sure to have the rear of your splines opened up so the disc will slide past (towards the transmission) 1/4-3/8" before you install the disc/pressure plate. I've got some information on the modifications to the transmission and how to complete the install the first time in my Webshots album.

I thought I understood what to do concerning the cutting and grinding of the splines but I just didn't trust myself . anyone who is considering this should take a look at Daves pictures. | | | | | Joined: Aug 2007 Posts: 1,859 Grumpy old guy playing with trucks, cars, and boats | | Grumpy old guy playing with trucks, cars, and boats Joined: Aug 2007 Posts: 1,859 | Or simply use a Camaro front half and S-10 rear housing and shift cover (Hybrid). The splines are longer, the bearing retainer is shorter, and the pilot is shorter.

I was a bit skeptical about using the 9-7/8 clutch disc in my 54 truck but it matched up with my pressure plate/flywheel bolt pattern and after 10K highway miles it's as smooth as the day I put it in.
Just a note....the Camaro input shaft has a different spline count than the S10 input shaft and if you're building up a hybrid to run behind a 235, you might have to hunt a little to match up the disc/pressure plate with the correct 235 flywheel.

The V6 and 4 cylinder transmissions all have the same 14 x 1 input shaft. If your running a ford trans, the early ones have the 10 x 1 1/8 spline and the later have the 26 x 1 5/32 spline. Jeep has yet another spline.

| | | | | Joined: Oct 2005 Posts: 1,317 Shop Shark | | Shop Shark Joined: Oct 2005 Posts: 1,317 | Correct...just wanted to make sure that anyone considering running a hybrid T5 be aware that they might run into some problems locating a 26 spline (9 7/8") disc to bolt to a 216-235 139 tooth 6v flywheel with a 10" pressure plate bolt pattern.
The Jeep boxes have 10 splines on the input shaft.
