So, I have now became a T 5 (S-10 / S-15 ) 5speed tranny fan (I really liked this "idea" , ever since I did my install = March 17, 2018 .
I also have a post back on page #2 . . . but, I did my install in my 69 Nova - - where-as in the car ; Most of those have / use the 10.5" dia clutch disc (which I posted that : part number in that post ( stock S-15 , 14 spline , 1" dia shaft , using the 10.5" dia
clutch disc) . It has been a great addition too my car ................. and, the reason for this "up-date post" .
Alot of you guys ; using your trucks , may need the same / similar "clutch parts - - or - - you may need the " Larger 11" dia clutch disc" .
When doing my 'search for a correct part number (that took longer ; than my actual install) - - -
And, this is an "Part Number Up-Date , for using an 11" clutch , for your 11" stock truck flywheels .

Summit Does have those type clutch disc , in the 11" , 14 spline , stock S-10 type up-grades . Part numbers - - - are 'Golden' - - -

Then, once you have a 'good part number' ; you could buy your clutch disc , from your "perferred vendor" .
Yes , I did alot of searching , for ANY useable clutch part number ; many people said they performed the "swap" , but never listed any good part numbers ............. well - here ya' go .
