I am in the process of repairing the longs on my car, pretty straight forward, except the jack posts had been removed by the PO. I have the replacement pieces and am not sure of proper set up. How far into the support should the tube go? Do I weld the tube to the support first, then to the car? Does the tube get welded to the car or just to the support? HELP!!!!! All of the photos and illustrations I can find really don't help.

I want to know too.

Measurements to indicate location might also be usefull.

Best way to locate the tube is to use the hole in the outer rocker as a guide. Weld the tube to the inner rocker, then install the support plate. The fender will be in the way and you won't be able to get the support in place. Make cuts in the support 1" down from the support's tube hole and bend the tab down to get clearance, then weld it back up. The bottom of the factory jack hole actually sits about 1" inside the inner rocker. If the whole jack post area was rotted and repaired flush with the rocker the new jack tube will stick out too far.

That's nice to know, I would have never thought to cut it. I am going to repair the area flush,
so how far out from the outer rocker should it stick? I had been planning to use the outer rocker to determine location.

Great Pix. Thanks that helps a lot. When your outer rocker is in place is the post pretty much flush?

Yes.

There's maybe 1/8 to 1/16 gap, but the plug fits snug when it's in so I don't think that matters. The tube also is snug against the rocker (no rear gap that I can see), fyi.

Excellent, thanks to everyone again. Your help is always appreciated.
