Differential Cover

[Ray C.]

Hi!

I need to secure a differential cover for a 1963. Is the 63-cover unique to the 63, or were they standard for all 63 through 67. I currently have a cover with a service replacement part number and will be looking for cover # 3830303

Thanks for any help!

The GM #3830303 differential cover was used for the 1963, 1964 and very early 1965 model years.

Caveat on late "303" covers

My early '65 [014xx] has a "303", as Joe states, BUT it is drilled for the later design plug (coarse tapered thread). So if you're planning on getting judged, this might show.
