81 interior parts

[Chris81]

I am new to the board and currently working on an 81 long bed with 90 burb front clip and doors (350/vortec heads/th400). The truck was mostly done, but has lots of small things that still need done.

I haven't messed with old cars for a long time, but had a 50 ford PU and a 64 impala among a few other projects that I played around with back in the day, before the wife and kids came along.

That was about 20 years ago, so I am kind of a newb, and I have a couple of questions:

1. Does anyone have any good sources for interior parts, mainly door panels, dash pad, etc.
2. Has anyone experimented with removing hail damage using dry ice?

Thanks,
Chris
