Projects 1957 Caballero

Can anyone tell me if the frame is the same between an estate wagon (4 door post) and the caballero (4 door hardtop)? If different, where are the differences?

 

Caballero featured a 122" (3.1m WB) gifted from the 1954-56 Buick model line, the GM 'B-body' on which the Caballero sat was shared across the 'smaller' Buick line (the larger Super and Roadmaster models had a 127.5" (3.32m WB) and with Oldsmobile. 1957 Buick Caballero and its sister, Oldsmobile Fiesta, were the first GM wagon designs to feature the 'pillarless hardtop'. Looking at Home town Buick, both share the same WB @ 122". Buick Century Estate aka Caballero.

Sweet. I have a caballero body with a chopped off frame. I know where the other wagon is that I'm hoping to use the frame.

 

I guess I'm reading it wrong, but it looks like the Super and Roadmaster wagons have the 127.5-inch wheelbase as opposed to the Caballero. It's unclear (to me at least) what series the Estate wagons were.

 

All 57 Buick wagons were built on the small series (Special/Century) frame. Technically they were all ESTATE Wagons. The Century Series 4Dr Ht (Model 69) was more commonly known as the Cabarello. The Special wagons were a 4 Dr post (Model 49) and a 4 Dr Ht (Model 49D) and were badged Estate Wagons. The Model 49 came with the manual synchromesh transmission (Dynaflow optional). All Specials came with. 250 HP V8 and 2 bbl carburetor while the Century series came with a 300 HP V8 and 4 bbl carburetor.

There were no wagons built on the Roadmaster/Super platforms.
