The crank shaft pulley I have for this car I'm building has space for two belts in it. This car is non a/c and has a manual steering box so it will only have the one belt running the alternator. I'm thinking that the lower pulley should only have one groove but can't seem to find any part info on that. Is it possible that all cars used the same 2 groove lower pulley regardless of options? Thanks in Advance !
The only single groove crank pulley I've ever seen on a Buick was on a 65 V6 car with manual steering and no AC
The nailhead cars from early 60’s and the 65-66 gs cars with no options used a single crank pulley they are somewhat hard to find! Not to many Buick’s big cars without power steering and they are a bear to drive . I drove my stick 65 gs without power steering for awhile and hated it!
My 66 3 speed had one but a lot of the parts from it were buried with my dads old barn. The car had manual steering and brakes, 3 speed, one wheel wonder. Sure was fun for a 16 year old!
There's a single on ebay right now. Prepare for sticker shock. Buick 364 401 Nailhead Single Belt Water Pump Crankshaft Pulley Set Pulleys | eBay
Yeah that is a bit much ! My two groove pulley will work just fine til I can run into a single groove pulley. Thanks Dan
