convert top frame

["Bob Merritt" <bob@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx>]

I'm trying to repair broken sections of the convertible top frame on a 62 
Chrysler.
How does one disassemble it? There are numerous flat head bushings at the 
joints -- it is not apparent how they come apart. Press fit?
I've learned a few things -- a Plymouth convertible top frame is shorter and 
narrower than Chrysler and won't interchange. A 64 Chrysler top frame is the 
same width but is longer -- interchange of pieces may be possible but 
remains to be seen.
Anyone have a complete 62 Chrysler convertible top frame for sale? It might 
be easier to replace the whole thing.
Thanks
Bob
