Adjustable lowering blocks

I'd get the axle where you need it with them and then pull 'em and weld them as you wont need to adjust anymore. Just to make them more solid (or make some steel with the dimensions you ended up with. Do the instructions say to run them with the threaded adjuster?

I was thinking the same thing about welding after. I have not bought them so not sure on the instructions. Maybe I can find them online, but Id weld after finding the happy place. Im just a little nervous after mini tubbing and then putting on sliders (and the car has possibly a history of a wreck....who knows?) that it will be a bear to align. The sliders are just tacked into place for now and the axle is not welded to spring perches until I get serious with a tape measure and a plumb bob.

Sounds like I should get busy with a tape measure and plumb bob first. Then make further decisions on moving axle. Any fixed points up front that arent affected by alignment are the suggested place to measure from?

Ha Ha.....always a little more to the story than started with aye?
