I'm wondering what length I beams were used on the 70-80's Econlines with disc brakes. I'm more interested in the length of the shorter beam. I'm tossing around the idea on making a custom IFS for my '51 Ford F-3 (equivalent to F-350). I would use the truck ones but my frame narrows to 32" in the front instead of the 34" frame the 73-79 trucks use. I'm hopeing that the Econline shorter beam would be around the same length.
Thanks
