KNOWN:

270 GMC motor, approx 1952
14 spline on S10 T-5 trans
Starter is 12v

I have the NAPA clutch disk recommended by Dave at Vintage Metal Works - who sold my bell housing adapter, but I received the wrong clutch kit from my supplier.. I think there's a difference in size and I should have ordered 4x4 or not???

QUESTIONS???
What is the part number [or application] for the correct complete clutch kit?

And how can I know if I'm running the right flywheel

Appreciate the help very much!

This is new territory for me. Some may find it hard to believe, but I have never installed an S10 T5 with 14 splines (only 10 splines after the Jeep shaft swap).

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
