Okay, Im rolling an 86 C30, crew cab 454/2wd

Im getting ready to do a clutch soon and want to do the rear main while the tranny is out...

BUT, Is it only back there on a one piece seal? 2 piece seals require oil pan removal instead????

Id like to order everything ahead of time so its all here ready to go rather than waiting a week for something to arrive whilst the truck is all torn up.


Ive read that 1986 was the cutoff for the one piece and the 2 piece seals were only in pre-86 trucks... elsewhere I read the that was only SBC engines..... nothing solid on the ol' 454

I have a mfr date in December of 1985 but is 86 model year

is there another way to tell which seal you have?
