[STATUTORY GRAPE]

I'm doing mock-up for my frame to figure out how/where my driveshaft loops are going to go and was wondering if anyone knows if when I have my axle narrowed,,,,, does the driveshaft generally go directly up the center of the frame ??? I notice on the 9" Ford, the axle tubes are different lengths and the third member is offset. I just don't want to get my driveshaft loops all welded in and have to cut them out and move them later on. Also, does the motor/tranny have to be perfectly level?

You can set up the rear with centered driveshaft while you are shortening the axles. Fords have been running with offset driveshafts for many years(1957?). The engine and trans are seldom, of ever, level. Usually 5-7 degree incline.

How do they narrow a 9" then, just narrow each tube the same amount or do they shorten one slightly more to make it centered?

You got it!. Ford has been using different length axles for years. Cut one shorter to center the driveshaft.

Lots of the time........you can just use another Ford axle shaft.

I have used a 65 Ford short side for a 57 Ford long.......

Find you a Hollander and look........

What is Ford's logic behind the unequal length shafts/axle tubes ????
