Want to convert drum to disc brakes in 68' Riv.

What yr is that there LUCY, my 68 Riv has the same shifter and center councle

 

It's 66'.:kodak:

 

Technically, the Electra and Wildcat are both longer/heavier than the Riviera...but all are considered full-size.

:Brow:

 

Yes longer car but the 68 Riviera has the largest production door on a GM car. Actually tied with the Cad Cupe de ville. 500 cid convertible car. Like the one Boss Hog had. I actually fit 5 posi carriers with ring and pinions inside the door at a local pick n pull. I paid for the door.
