I was going to install a 1987 C10 IFS on my 51 but the tracking was to wide and without taking about 1 7/8" out of the center of the saddle I was going to have to put 1" spacers between it and the frame. But I was told from several people that it fit good on a 58 thru 66 ?? and with drilling a couple extra holes on the frame it was almost a bolt on ?? its heavy duty enough for just about any engine setup you go with, look into it and see Im not sure but thats what I was told
good luck
