You don't need a jig, aftermarket double adjustable control arms take a previously difficult fabrication job and make it a bolt in procedure. Contact Rick, username Iceman he'll fix you right up.

The information in the Tech section needs to be updated. That was written before there were swap control arms being sold. If you want to install a 12 BOLT (not inch) into the G-bodies, you only need the modified upper control arms. You can use stock or aftermarket G-body lower control arms. You will most likely need to relocate the coil spring perches on the axle tubes to locate the springs in the stock G-body location. Keep in mind these rear ends are wider than a stock G-body, so it will require more backspacing on your wheels than a stock G-body rear.

Go here for width comparisons: http://www.maliburacing.com/faq.html#rearend_swap

Check out the other sponsors, they may have them also.

If you really want to fabricate something on your own, you can use a G-body rear frame section as a jig to build your suspension around the 12 bolt you have. I have seen guys do that with Ford 9" rears before.

Hope this helps with what you're looking for.
