1987 iroc z with 14 spline t5??
hello to all,i have a 1987 iroc z with lb9 5 speed g92.my trans was leaking oil in between the trans and the bellhousing.i removed the trans to fix the leak and decided to go ahead and replace the clutch while i had the trans out.after looking at the old clutch i noticed it was a 14 spline shaft.i was searching for a new clutch and they where all 26 spline.as for as i know my car is all original,could it have come with a 14 spline borg warner trans???what clutch do i use???

Sounds like somebody has already applied the 6-cyl hack to your car.
NO it ABSOLUTELY DID NOT come like that.
What a bummer. I might commit some form of bodily mayhem if I had paid G92 IROC money and discovered I had got .... that ..... instead. Somebody has seriously sodomized your car.
Either find a V8 transmission and use a V8 clutch; or, use the clutch from a 6-cyl Astro van. Which SUX because it will keep the ridiculously wide ratios of that 6-cyl garbage transmission. If it was me, I'd be scouring the earth for the right trans, rather than figuring out which clutch will preserve the cheeeeeeep-out PO hack.

What year did they change to the pull type clutch? ( I am converting to a t56, but wantnto retain the conventional style clutch.)

Precisely.
And one of the benefits of G92 was the ratios in the transmission, which you paid for and didn't get. You SHOULD HAVE got a .73 5th but instead you have AT BEST a .63.

Yeah since the Astro is basically just a S truck with a big box on the back, if the S truck came with a 4.3 (I haven't the foggiest clue about that, it's all 6-cyl stuff which I avoid every possible atom of) it should be the same clutch.

Yup, that is true; at worst, you might have to change the drive gear also, if it's not the right one. But in any case if your speedo is correct now, you can transfer whichever of those parts you need to, right over to the other.
