Thanks guys. I appreciate the replies.

I was looking at Kanter, and they have the brake parts, but I will check out CPR too - I had forgot about them.

I have 235/70-15 Radial T/A's on the back of my '57. They are mounted on 15X7 American Torque Thrust wheels. I have air shocks on the back which are still available from many sources. Brakes are also available from multiple sources, just watch for country of origin on the parts you buy.
Door panel backers are readily available also, same as Chevy as is the package shelf, weather stripping and all other seals. Ditto for glass! seat foam is more like the '55 and '56 Chevy.
CPR is a great source for what you need including the battery hold down and sun visors and mounts.
I have found most of what I need or want on ebay and as you will find out wheel bearings are always handy to have on hand both front and rear along with seals.
I try to buy new old stock for bearings as I don't trust the new stuff from off shore!
Hope that helps! KK
