engine cradle exchange

[AmadeusCharger500]

Is it possible to exhcange the cradle from 73 with a 71 or 72?
Mine is rusted out and I am only finding replacements for 71-72.
Is there any difference other than the large bushings?

71/72 are totally different from the 73/74 K-members

Is my only choice then from a 73-74 b-body?

I think you can use later K frames as well but not earliers.  Im not 100% sure but I think the K frames from 73 to like 79 (or close) in Cordobas, Chargers, ect... are the same.  Of course, with this style of K frame (spool mounts) you need the right k frame for the motor ( /6, SB or BB) or else you need to buy conversion mounts.

Seems like there should be a handy all-encompassing compatibility chart of this stuff somewhere.
