I have a 1968 Ford F100 with an FE big block. Can this system work on my vehicle and still retain the existing engine crossmember? I ask because I want to be able to convert back to the I-beam suspension if needed, and do not want to cut or modify the crossmember. I just want to remove the I-beam suspension, mount the straight axel and add spring pockets and shock eyes to retain my original geometry.

Hello, I am restoring a 1947 Dodge WD15 3/4 ton truck and was wondering if you had any front brake conversion/suspension upgrades available that would work on this. I didn't see anything on your site that would handle the 3200lb net weight of the truck, but I am no internet guru either. I'm wanting to also add power steering if that makes a difference for you all.I look forward to hearing if you have any products, or advice you have. Thanks much, Kevin Cook
