1967 Deville Convertible Frame

[dmm663]

Can anyone tell me if the 1967 Cadillac Coupe Deville frame is the same as the Deville Convertible, or is there any other frame that is the same?

David,
Don't know for certain, but in my experience, convertible frames have more heft (weight/strategic integrated structural steel) --- for example, the 80's Eldorado convertibles were 250 pounds heavier than the coupe-- (roof on sedans and coupes is lighter than the addition frame structure that keeps the car from bending!).  James

 The answer to this question is a surprise to me. Older models did use a different frame on conv.

  Part # 1488863 fits 1965-67 all except 60s,75,CC,Fleetwood Brougham & 67 Eldorado (All with 129.5 inch wheelbase)
       Hollander note; On conv. models rear axle stop brackets need to be added or removed.
       Cadillac note: to order new ones.

  67 Shop manual section 2; Conv uses some different and one more body mount.

Convertible frames have heavier gauge steel in critical places to control flexing.   Especially at the side rails.

Plus, there are different body mounts in places.

Plus, the Convertible body has strengthened Sills to further stop flexing.
