4 frame plates, long enough to fit in pretty much any chassis from a Model A to an F100 pickup
All necessary grade 5 zinc plated hardware

This kit will work with all SB Chev blocks which have the 3 bosses on each side of the block. This would be all blocks, including LT series, up to the LS series except some 1955/6 265 blocks that were cast without the side mount bosses.
