When I bought it, it came on a BARE Frame, no axles or springs, not even the spring mounts...SO...I have purchased all the parts to install a Mustang II front crossmember...but having NO axle underneath it, I have now way of finding my centerline...was hoping someone out there has done this before and could let me know what the measurement is and where to measure it from ??????Any and all advice will be much appreciated....might be easier to email me directly, don't get to this site [email protected] | | | | | Joined: Apr 2005 Posts: 2,832 'Bolter | | 'Bolter Joined: Apr 2005 Posts: 2,832 | We build a lot of rods from scratch so maybe this tip will help. Bolt a front fender to the cab (which doesn't need to be on the frame) and then use a tire/wheel combo that is going to be on the finished project and just place it in the wheel opening in the position you think looks the best. Now measure from the front cab mount hole straight forward till in line with the center of the mock-up wheel. Now do this same measurement from the cab mount hole on the frame forward and mark the frame rail. This will be the axle centerline that puts the wheel/tire where you thought it looked the best. Also, forget the factory mounting of the rear end because GM mounted it so the rear tires are 1.5 to 2 inches too far forward or at least this is so on the 47-54 AD's.

Not to get off topic, you touched on it but I have always wondered why the rear axles never were in the center of the rear fenders on AD trucks. Seems like the 3/4 and 1 tons were even worst that the 1/2 ton trucks.

There was no suspension under it, so I decided where I wanted the center of the wheel and made that the centerline. The great thing about customising the truck is that you can make it look how you want it to. | | |
