Could i use a 1994 caddie deville sor a parts car for my 1995 deville

i recently purchased a 1994 caddie deville (lovely car) but i wanted to also purchase a parts car as to save money on costly repairs but my question is will a 1994 caddie deville work as a parts car for my newer 1995 deville?

These are the cars here:

maybe some parts but if im correct the 94 deville has the 4.9 in it and the 95 has the 32V northstar so for engine parts no but for cosmetics and interior yes
