Where should I put my engine crossmember? (updated) I've been planning on moving the engine back about an inch. I'll probably move the cab back 3"... maybe as much as 4". Going 56" front springs and moving the axle as far forward as I can. The idea is to get as much weight as I can off that front axle... The further you move the crossmember back the distance between the frame rails grows. You also run out of bolting-in room on the top of the frame. Bare front (boy, it sure would be easy to go coils right about now...). The crossmember is being held in stock position with the crapsman screwdrivers. Stock location for the passenger riveted crossmember (look at that wasted motor mount, mon): After moving the crossmember rearward about an inch... the screwdriver marks about where the hole in the crossmember is (and it's real close to the edge of the frame) See how it moved away from the frame as you push the crossmember rearward? Also notice that the hole in the frame that the crossmember sort-of lines up with is the hole for the brake hose. Also, as you go rearward, the frame gets taller as you can see the gap. The shiny part there at the top is the edge of the hole in the crossmember.
