A metric car is a 1978 or newer full framed car Monte carlo, cutlass, grand prix,etc. A camaro is not. Most people that put a 9 inch in use some sort of jig to rig it up. Others can tell you better than I.

not a lot different than a metric except for the torque arm bracket,alot of the chevy high performance magazines have them in there but they are expensive $500 +

Every track I've ever been to has a couple of guys who are wonder-workers with a welding rig. Ask around-I'll betcha there's someone who races at your track who'd be happy to take it on. The internet is great for ideas and sharing experience and knowledge, but there isn't anything better than getting the car up on the jig and working on it yourself!

Hello cveclipse, Welcome to the forum. It is somewhat difficult to explain how to build fixtures without photos or diagrams. My previous attempts have not exactly landed me any literary

There are any number of companies that can build the 9in. to whatever specifications you desire. Some have an ad in the back of CIRCLE TRACK. If you are intent on building it yourself, perhaps we can discuss the criteria involved to, at least, get you pointed in the right direction.....

The first hurdle to overcome is finding a rearend that will work.........Ford built the 9in. in many different configurations, differing widths and pinion offsets. You will notice that the pinion is offset to one side, it is not centered between axle flanges.

I am not real familiar with the newer camaro rear ends, but, for a guess,the pinion will only be offset an inch or so......

Ideally, I want to keep the driveline straight.......I want to keep the yoke in the stock side-to-side location. I would like the new rear end to be no wider than the stock one.......(I would prefer it to be 2in. narrower) Generally, a compromise will have to be reached. Usually with the left tire sticking out too far.

Depending on which rear end you have, (while keeping the yoke in the stock location), the right side tire may or may not stick out too far. The right side tire may or may not hit the right side frame rail. In either scenario, your best bet would be to find a different rear end. Unless, of course, it is close enough to compensate for using reasonable wheel offset.

After you have a suitable candidate, it is time to build a "jig". A Jig is simply a fixture to hold a rearend and locate the pick-up points. It can be as simple or elaborate as you care to make it.

For this discusssion, I am going to assume that your stock rearend is square and that the pinion angle is proper. If this is not the case, we can discuss it further.

A steel table would be preferable for the jig. However, you could make a rectangle out of square tubing for the fixture.

First, you need to make a "cradle" or "stands" to hold the rearend. You could cut a piece of 3in. pipe about 2in. long, then split it down the center. You would now have 2 half moon shaped pieces. (or you could use some angle iron). Weld a tube about 8in or so to the bottom of the half moon pieces......Then weld these to your "table"..............At this point,You now have a "table" with two "stands" welded to it...........

Place the stock rearend in the stands,plumb the yoke, clamp or tack weld the housing to the stands..........

Now to "jig" the pick-up points.......Cut a piece of tap tube the length of the stock bushing...........Place the tube in the trailing arm mount,slide in a bolt, tighten..............then weld a tube from the table to the piece of tap tube......Do this for both sides...........That takes care of the trailing arms...........

Build a similiar fixture to locate the panhard, shocks and swaybar...........

For the torque arm, careful consideration must be made......if you build a welded mount,you must insure clearance for the third member instalation.......You may wish to consider building a bolt-on torque arm mount...........

Mark the centerline of the pinion on the table, and remove the stock rearend from the jig.

Place the 9in. in the jig. center the pinion on the mark previously made, and plumb the yoke. Clamp or tack weld the housing to the stands.

Now, to put it simply, build the brackets to fit the jig. For the trailing arms, it is a fairly common practice to cut the mounts off the stock rearend and reuse them. Or, you may fabricate some new ones from some plate or flatstock............

There are a variety of aftermarket bracketry for the panhard and shocks. In some instances, you may be able to utilize the stock pieces for these mounts also.

I hope that you find something here helpful. If not, I am certain that, If requested, I can confuse the issue even further.........LOL

Good Luck,
