Does anyone know of anything that used a disk like this the biggest one I can find without going over is for a 1990 lumina but that is only 9.75 in. I went the light truck route but no luck finding it. I'm trying to get a v6 tranny to bolt up to a 350 with a clutch that will last.

 

im using an 11" with 14 spline ahft from an astro van, but it probably wont fit in the stock bell housing
