Hey all, I'm currently in the midst of an IFS swap for the front end and may have jumped ahead of myself.
I already have my frame stripped completely and talking to Heidts the kit they offer is meant for a 1/2 frame but told me if i give them the dimensions of my frame they will cut one to fit, perfect! but the problem I'm facing is i don't remember where the stock front end was... there is a '54 gmc sitting in the highschool shop right beside mine having the same front end swap done to it, and measuring that frame (from firewall to end of frame rails) and comparing it to mine, the frames are identical up to 24" from the firewall, and then my frame for the 1 ton is 8" longer...

if i remember correctly the one ton uses the same front fenders and hood as the smaller truck... correct? so why would the 1 ton frame be 8" longer?
and if anyone happens to have a measurement from the front of the frame rail back for where i should mount the ifs would be much appreciated!
