1975 or 76 Eldorado convertible
 

Hi I am new to forum and I am looking for complete rebuilt CV joint assembly Right and left does anyone know where is the best place to buy parts for older Caddys
Dash parts
Body parts
Thanks

"Dash parts" and "body parts" are likely to be Treasure Yard-only items at this point.

Some switches may be supplied in the aftermarket; you could check local parts-houses such as O'Reillys, NAPA, Advance, etc.

Same goes for CV shafts. Wouldn't surprise me to find that they're available new (Chinese knockoffs) or rebuilt from any one of several parts stores like those listed above.

As far as CV shafts, they're not hard to rebuild as a weekend project IF you can get new boots to seal the joints once pulled apart for cleaning and repacking with grease. There was a time when oversize ball bearings were sold to rejuvenate slightly-worn CV races. I think those days are gone. Last time I looked, my favorite parts store no longer listed boots for these vehicles. Ideally, you catch torn boots before there's too much intrusion of road-splash, grit, dirt, etc. that causes wear to the ball bearings and their races.
