Building this is a pain in the butt and I don't want to do it again. I wish I wasn't poor so I could have just bought a Maximum Motorsports one. Oh well, at least I can build one.

I just have a little update. I spent a couple of hours on Sunday getting everything lined up and the cross member tabs secured with C clamps. Then tonight I welded all the tabs in place. Next up will be lining the TA up so that I can make the rear arms and setting the pinion angle so I can make the front ones.

Looking good Ron!

Thanks Adam. Hopefully it performs as good as everyone says it will.

If you made any jigs or templates, you could more easily make and install more for cash moneys. :)

I copied Maximum Motorsports torque arm. It would be illegal to make them to sell and I wouldn't do that.

Is the design patented?

It doesn't look like it but I wouldn't do it anyways. I'm okay with building it for myself but that's it.

It is, MM has sued over it before.

I got a little more done today. I cut the tubing for the axle brackets and got them welded on. Then I cut the tubing for the front of the housing to set the pinion angle. I only got the drivers side done though. Tomorrow I'll make the one for the passenger side. And then finish welding them to the arm.

Sorry for the bad pictures, I'll take better ones tomorrow.

I made the pinion angle bracket for the passenger side and took a bunch of pictures this time to show what I put into making it. Once I got it all made and partially welded I dropped the TA and crossmember so I could fully weld the brackets. I was finishing up the top sides when I ran out of shielding gas. So I'll have to go down Tuesday some time and get a refill so I can finish up.

This is how I start. I measure from the diff to the arm and then cut a piece of 2in plate to use to find the angle for the top and bottom. I hold the piece in place and then use a protractor to get the angles. Then I transfer the angle to the tubing and then cut it.



After that I cut a 4in piece of round tube for the bolt and bolt it to the diff. I drilled the holes out to 1/2 for the bolt so that it would sit centered. then I hold the tubing for the bracket up to it so I can mark it to cut the hole for the round tube.















Once I have the hole cut out I bolt the round tube back up and then hold the bracket in place so that I can tack it.





Then I pull it down so I can weld it.



I then bolt it back up so that I can weld it to the TA.



I only weld the sides because the top and bottom welds come out better with it off the car.





You can see in this picture when I ran out of gas.



Here's what it look like so far.



I also picked up a freeze plug for the crossmember so I installed that.



The final thing I did today was drilled the 9/16 holes in the diff and then cut the back of the TA to give it a little more ground clearance.
