    What is involved in shotening a Long Wheel base frame to fit a blazer body on it? Curious if anyone has done this. I have a LWB frame and found a blazer body cheap.

    I had a lwb and cut it down to put a short bed on it. we cut the frame cause it seemed easier and my dad has done it to three trucks now and none of them have ever had any problems so I trusted him when he helped me do it that way. plus if you just move the spring hangers you wont have the hump in the frame for the axle to articulate but Im not real sure that you even need it. my frame has held up just fine and is still straight or at least as straight as it was before but I think it would be stronger and maybe safer to move the spring hangers. If I had done it myself I would have done it that way but like I said my dad helped me do it and I trust him. Im gonna go back and add another plate to the outside and maybe a cross member so Ill at least feel a little safer about it.

    to me it just seems remove the rivets, sliding the brackets forward and either drilling and bolting or weld them in place. hell i could do it in a about an hour allsaid an done. i dont think the same can be said for a frame splice. Also your adding a spot to fail. not saying its going to happen but its another thing that can go wrong. Also the hump in the frame isnt going to affect anything

    here is an older pic it kinda gives you idea. I move my rear forwared about 13 inches then put a crossmeber in betewenn the spring hangers to reduse the stress on the frame. I have never had a problem with not have the axle hump.
