I do collect info to help others however, so I'd like to know the part numbers you are dealing with.
I've spoken to Dave Farwell on a few occasions and he's a great guy and a great resource. Two thumbs all the way up!
I know Speedway Motors sells several 14 spline clutch discs that work with T5s. You would want the largest diameter that your flywheel and pressure plate can handle. Here are some links to the clutch disc at Speedway Motors. This Speedway disc is 9' which may be too small. Speedway 10" disc. Speedway 10.5" disc Also, these are usually in stock at Rock Auto.
1988 Astro van with 4.3L engine clutch disc — 14 spline and 11”
Option 1: M-PACT clutch systems part # 384212 from Rock Auto
Option 2: SACHS BBD4212 from Rock Auto | | |
