LCA and Panhard Specs Please

Does anyone know the bolt hole to bolt hole length of a oem panhard bar and lower control arms? Need it for a baseline on installing a new rear end and suspension.

I have mine all pulled apart. I will dig out the parts and get the measurements for you.

Panhard bar = 43" center of hole to center of hole
LCA = 19 3/16" center of hole to center of hole

That was done w/ tape measure and eye-*****. No precision calipers or anything for those measurements.

Well, now they are published for the next person who needs them. Heck, might be me by the time I put mine back together.

You sure its 3/16 and not 5/16?

My after market Lakewood's measure 19 5/16.

Re: LCA and Panhard Specs Please

My measurements were eyeballing the center of each hole, so being off my an eighth of an inch is possible.

When I installed my Herb Adam's adjustable LCAs years ago, I ran the mounting bolts through the original LCAs and then into the replacement ones. Adjusted as needed to get them equal and tightened the jam nuts.
