Default Dorman 34158

Hey guys I purchased a dorman 34158 off a local guy he said that it works/fits as a direct replacement for my 1990 base corvette. I've looked everywhere online for an actual bypass pulley other then the tpis one bc I will never deal with guy again. From what I can find this pulley will not work for my l98 does anyone know of one that will ??? Thanks in advance. Just found a video where a guy is using dorman 34224 but his corvette looks to be an older l98 im wondering if this will work on my 90 ?

Taylor

That Dorman 34158 is an A/C delete, not an air pump delete.

I think tpis is the only one that makes one that will fit. Not sure what your issues are with them but might order one that’s guaranteed to fit.

As stated before I ordered headers from the guy 16 months later they never arrived kept saying 2 months took 3 months to get a refund. Guy is a clown 🤡 but its all good I found a used one here in town.
