Scott,thanks for the reply. I have a 54 GMC 250 panel (1 ton) 137" WB. I've pondered for years over the "right" IFS to install,I want to keep it as close as possible to the original ride height. It came with 7.00-17 tires (31 5/8" OD),I'd like to use a modern radial of similar height on wheels with 5 on 5" BC. It will not be used to it's original load capacity,mainly just a driver. Could your crossmember be installed using tubular upper control arms & a spacer below the frame to achieve this ? What is the current cost of the crossmember ?
