Hello, I myself don't know the answer to your qeustion however I know where you can possibly get some good help. Try going to
www.summitracing.com, www.gr8ride.com, and or
www.edelbrock.com. If you check out these sites they will have classic car parts for you and if you are un-sure you can e-mail them with your qeustion they always love to help. Also another resource is Autozone. They answer automotive qeustions really well. I hope I have been of some help. Good luck on your restoration project of the long living and beloved Oldsmobiles we all drull over [img]smile.gif[/img] bye - Countrychick
