Achipmunk, ** If did not know better I would say the orig. body mounting blocks in your series of pictures were the one's I removed from my 53 Suburban nails and all. By chance do you recall what the height of the blocks were? Mine measured 1-5/8 inch's but the kit I got from Jim Carter the blocks measure 2-1/4 inch's. Thanks for the pictures. Any help you can provide is greatly appreciated.
