Description
For sale is a NOS 3978759 M-22 4 speed Rockcrusher mainshaft. This is the 31 spline T-400 size output shaft. This was used in 1971-74 GTO/Judge and Firebird/Trans Am with Muncie 4 speed. This number crosses over to Buick,Oldsmobile and Chevrolet models but I only have Pontiac parts books so please check your application before purchase. If you want a used shaft I have a nice one I can list. I know the Chinapops are cheaper so if you want cheap then go buy one of those. The NOS seal for this tailshaft is in another auction. Buyer to pay 30.00 shipping and payment in 2 days by PayPal or cash in person. This will be sent insured with signature confirmation so someone will need to be at your confirmed eBay address when it arrives. No P.O. boxes or Canada addresses. Thank you.
