What shifter boot do I need

1976 CJ5 AMC 258 i6 / 4.2l cid engine and 3spd tranny.The one I got was too small.

I am guessing you have a T-150 Transmission .
How about this boot:
Amazon.com: Shifter Boot 1967-1979 Jeep CJ5 & CJ7 w/ T-150, T-14, T-15 Transmissions # 948185: Automotive

But do you have a body lift? If so the OEM boot won't work. The shift lever moves too much. You may need a longer boot.

You could also use a CV Joint Boot and cut to fit. Make a ring of fiberglass around the base.

Seen a couple guys do that.

But usually a stock replacement one should fit, when i clocked my Dana 300 i reused the original ones, i just moved them around a little...
