Front carb is 3645SB which looks correct. Back carb is 4053S. Anybody know what that carb came off of? Thanks Rick
Rick; My Hollander interchange comes up with same application as the 4453 for the 4053S. This is; Buick 65-66 ex. LeSabre 8-401 Carter, auto trans Buick Special 65 8-400 Gran Sport auto trans. Buick Special 66 8-400 Gran Sport auto trans. These are single carb applications. Your rear carb should be 4051 to be correct for the 65-66 dual quad although it may run fine with the carb you have. The linkage would probably work also. Good Luck, John Zeleznik
Not sure about your carbies Rick, but here are the '65 codes 401 Automatic 3921S 425 Auto 3923S 401-425 Syn. trans 3922S Dual 4 BBL all front 3645S Dual 4BBL rear-auto 3925S Dual 4BBL rear -syn 3924S Buick Service Manual 1965 If anybody finds a 3924S, I'm interested!!!
Larry; Yes the 3925 is also correct for the rear. I missed that one. Ted; I will look in the carb pile tomorrow. John Zeleznik
