I think they will work from either a 350 & 455. Also looking for 2 groove pulleys for crankshaft & cooling fan. Please let me know if you have some lying around the garage. Thanks!

 

I believe I have the 2-groove pulleys for you. I'll check tomorrow and post some photos and measurements if you'd like. I think the alt brackets are slightly different between the 350 and 455, but someone else here would probably know for sure.

 

That would be great! Thanks. I'll wait for your pictures. Anyone got
a Non AC Alternator set of brackets? Please?

 

I have a set of the alt brackets. let me know.

 

Sorry for the delay....here are the photos of the water pump and crankshaft pulleys that I have. The water pump pulley measures 7 1/4" across and the crank pulley is 6 1/4" across. If I remember correctly they came off of a 425 non-a/c car. I have a spacer that I can throw in for the water pump pulley if you need it. Let me know what you think....

 

Sorry for not responding quickly. I couldn't get back into Classic Oldsmobile.com last night or all day today. I think those will do the
trick for me. Please let me know what you want for them, including
shipping to Crestwood, Ky. Thank you! Eric

 

Which cooling fan are you looking for? I have a four blade non a/c with spacer.

 

I've got a fan for it already. THanks!

 

I got both brackets and the pulleys that I needed. Thanks to everyone on this site. Happy Holidays everbody! You guys are great. Eric
