I'm currently running a 4 speed saginaw in my 235 powered 54 3100, and I plan to install an S-10 T-5. I've read that an astro van uses an 11 inch 14 spline clutch that will work with the trans. Will this clutch work with my current bellhousing and pressure plate? Will I need a new pressure plate or another clutch that is different diameter? I believe I have a 10 inch clutch right now. Also from what I understand I will have to shorten the input shaft.
