got busy, haven't had much time to work on the cruiser, been working on being a dad first, easter, swap meet and work have killed some of my cruiser time..
got about 8hrs today, ran out of sandblast sand, and sheet metal, so will have to make a trip to town tomorrow.
so I finished working on the frame, taking 6" out of the middle..
I know others have shortened an fj80 frame but this is how I did it, first remove the lower rear control arm mounts, then mark the frame for the rear cut I started on the outer 4 inches behind the inside joint on the boxed frame there is a reinforcement on the inside of the box, I cut with a die grinder there making sure to not cut the inner reinforcement. Cut most of the way thru then use a chisel to split it and clean with a grinder.. at the same time I took the weld off the inner joint and the top and bottom of the frame rails, this gave me a 2 piece frame.. then shorten the inner and outer square it all up and if everything is right 106" wheelbase, I ended up a little shorter 105 3/8" but I think that is due to no weight on the frame because I removed 6" and both sides are even..
the reason for keeping the inner reinforcements is one strength and two it helps align the frame when you put it back together. I am still going to make an outer c reinforcement extending 3-4" ahead and behind the weld joint, for some extra strength..
