What is the overall width on the front wheel/tire from outside to outside ?
I am curious because I am working on the same swap on my 48 3600. I just finished boring out the center holes on a set of 2007 Jeep wheels. They are 17 x 7.5", 5 lug on 5.0" bolt circle and have a 45mm (about 2") positive offset or about 5.75" backspace. I narrowed the 78 crossmember 1.5" for a perfect fit with the 3600 frame (this one is narrower than the 3100 frame). That said, this combination gave me about 68.5" from outside of tire to outside of tire. I am using a 235/65/17 tires front and back. I do not have all of the parts for my front end sheet metal yet and would like to know if this is going to fit within the stock front fenders ?
Mobileortho - your truck is looking good.
Oldsub - I narrowed the crossmember by using 1.5" wide masking tape around the center and cutting along either side of the tape with a sawzall. No angle cut was necessary. With some trimming, I welded the cut off piece inside one of the sides using several plug welds. I then used this as a guide to mate the two halves back together. The assembly was bolted to the frame and then welded back together for a perfect fit.
