Speedway part number 91639035. This gasser axle kit is made to be universal, meaning that you can adapt it into just about any vehicle. To give this axle a place to mount on your frame, you may need to modify the original frame rails or replace them with square tubing. The axle is available in pre made widths from 44 to 50 inches, and we also offer custom widths. Our steering and brake kits add about 8 1/4" of width from hub to hub. If you want the track width to be about the same as it is no, I would recommend you measure your current hub to hub width, subtract about 8 1/4" and that will be your axle width.

We have had several customers install these kits on the early-‘60s Ford cars. Every one that I saw used a fabricated “frame stub” that extended forward from the base of the firewall and incorporated an angle brace that came down from the hood hinge area. These frame stubs were constructed by the individual car builders, of square and rectangular steel tubing. They would incorporate fabricated, steel sheet, engine bay side panels and a portion of the original Ford radiator support. It was a fair amount of work but if done well it made a very sturdy and attractive package. If you would like to discuss this further, please call us at 1-800-979-0122 and we can perhaps give you some further suggestions for your project.
