I have had both, my parents bought a 64 Custom 880 brand new, had it till 89.

I was driving it in the 80's in high school. Finding body stuff was hell, as it was a one yr bodystyle. There was a 2 door in a junk yard that i got most of he stuff off of. It was a stock driver.

The mechanicals were pretty easy to find, regular mopar stuff, took a long time as in the 80's there still wasnt a good after market supply.

1965, pretty much the same as Polara, Monaco, the 880 was just a upscale Monaco. Most of the C body chrysler stuff will work, and its available, just gotta search for it.

Bad ass car, if you search the 62-65 mopar site, for 65 880, i think the black one they have on it was mine.

Black, with blacked out windows, red interior, lowered on chrome reverse 60 series rims, 383 with a cam and 727 with a manual valve body
