    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

    I thought the rear carb for 65/66 2x4 was a 3925.:confused:

    Larry; Yes the 3925 is also correct for the rear. I missed that one.
    Ted; I will look in the carb pile tomorrow.
