I have a plenum 10077151 that fits 1990-91 Camaro L98 350
I got it with a bunch of parts in 2010, but it appears to be intact.
I'll refund your purchase price, (except shipping), if it does not function properly.
Price $25 plus actual shipping costs.

Thanks

 

How much for the map bracket and bolt ?

 

Hmm... I think @blacksunshine'91 was looking for a 91-92 plenum awhile back.

 

Thanks
