Correct, I have 1.5" wheel spacers for the rear that change the pattern to 8 on 170mm.
I have been getting the radius arms welded together and holy crap these things are awesome! They have to be the coolest thing I have ever built; the way everything lines up and fits together is absolutely amazing! These are beef too; each one weighs 35lbs after welding and without the joints, and the skid plate weighs in at a hefty 115 lbs! It is all fairly straight forward; however, I did try and get all fancy on the first one and weld in the backbone, it didn’t work out too well for me and I ended up having to cut a bunch of my tac’s apart because I couldn’t get everything to line up as good as it should. I’ll try and put some pictures to the sequence I found to work the best. One more thing, MAKE SPACERS FOR THE JOINTS! I didn’t at first and quickly realized that the heat will tweek this stuff just enough to where you’ll be fighting the joints.
First lay out the bottom and the backbone, they interlock, can’t F’ this up…
Next put the middle piece in that goes under the upper arm, this has tabs on it to align the outer pieces.
Next put the 2 sides on, note the ¼” spacers I used to lift the 2 sides up fairly even with the bottom plate and clamp it together.
Put the top piece on.
And then the top end by the axle bushing.
I used a 12mm bolt and 2 nuts to spread these plates apart a little during welding, worked like a charm.
Then start tacing all you little gussets on, on the uniball end I installed the set screw and the zerk so I didn’t get any weld in them.
Then the backbone cover piece.
