My sm465 I got for my 4.3 swap had the rolled steel clutch fork, anybody know what applications the better "cast" one was in..
thanks

My sm420 has a cast steal one in it

not sure what apps, but I just went to the chevy dealer and asked him for the cast fork. He knew just what I wanted.

No kidding, thanks keith, I had heard they were no longer in production, but i guess I will have to climb over the counter at work on tues and bug the parts guy, see if he knows his shit or not,lol...
