Is bolt pattern on a 1954 Caddy the same as a 1978 Seville?

[John Mann]

Hello friends:
I have a fine set of 1954 wire wheels  and a 1978 Seville. I would like to know if these will fit the Seville without having to take off one and try it.
I know that mt 1976 Seville had a different pattern but am thinking that the 1978 is the same as most other Caddys.
Thanks for your help.
Best,
John

The late 70's seemed to be when the full sized cars could go either way.  I had a 77 Delta 88 that used the smaller pattern that matched my 82 Regal and 57 Pontiac. Everything else I had was the larger one that matched the 2x trucks.  Hope some of the experts will be along soon to tell you more than I can.
