81 versajet 2 carb./ vics and Years??

[Carlos Torres]

I'm trying to find out what years of gm/chevy vehicles have the versajet 2 carburetor. I need to get a discharge spring for the carburator pump.

I feel like you could find the carburetor number on the carb and then find it on quadrajetparts.com they sell parts for Quad, Duel, Mono, probably versa, and everything else in between. Whats a versajet?
