i have a 89 irocz with a 350 tpi its been swaped with a t5 and i was trying to get a clutch kit that fit it i was having problems i wonder if anyone can tell me why i would be having problem fining a clutch kit

 

you should have no problems. You need a kit for a 305 f-body, 1pc rear main, 10.5" disc with a 153 tooth flywheel.

if you are searching for a clutch kit for a 350 powered f-body, you wont find one specifically listed for that application because it did no exist from the factory

 

There are two options
86 to 92 305 V8 5 speed f-body application.
Or if you ended up with an older engine with 2 piece rear main seal that happens to have TPI on it,
then 84 to 85 305 V8 5 speed application.

The clutches aren't different. The flywheel is.

Either way, you should post pictures of what you're "having problems" with. And part numbers of what parts you're "having problems" finding.

Communication is key.
