GM A-Body Weld-in Tubular Frame Kit (64-72)
PTSfab weld in frame kits are here! If you are looking to swap in an engine combo that needs extra room or you're trying to just have extra room for ease of maintenance, this is the ticket. Fully tig welded and constructed of Chromoly. Turbo systems, larger headers, dry sump accessories and large oil pans are all difficult swaps for these older chassis with the stock bulky center section of the frame. these kits do not require cutting the factory frame rail at all which also is a legal modification for most true street and other limited street classes that do not allow "tubular front"
All factory body components can be installed as they were, no guess work!
