Hi a couple questions... My first resto on a mopar. I was noticing the left front of my car is slightly lower than the right. Is that shimable? Its only about a inch or so, I didnt see any bends or damage to the frame and at the firewall it almost measures even to the ground, the frame seems to measure even to the ground,its the body. Also, the motor mount bolts seem loose at the front should they be a shoulder bolt or a spacer installed. The ones I looked at to buy are not thicker at the top. Not sure what to do any help is welcome.....

I assume your car is sitting on its tires. Check the space between your lower control arms and the frame. Measure the distance between the arm and the frame. If it is different, your torsion bars need adjustment. The bars are adjustable at the pivot located under the lower control arm. Use a 3/4 socket and tighten the low side up 1 full turn, bounce the car on its suspension and measure again. Go slow, and keep track, with small adjustments as it doesn't take much to change ride height. After each adjustment bounce the car to settle the suspension. After you have leveled the car take it to a front end shop and have the alaignment checked.

Thanks but it looks to me to be in the front nose of the body itself. Im not sure if it was hit but it dosent look like it.I will look at the torsion bars again but we checked and that part looks level.My front end is off the car,and when standing back looking at the radiator support the right side looks lower and the firewall looks straight.Kinda crooked? Is there ever a case to put shims under the subframe?

Your car doesn't have a subframe per say. It is a unibody with welded frame sections, not a bolt in style subframe. How does the rear end of the car sit, is it level side to side? Try to measure from a level floor to the top of the inner fenderwell, should be the same side to side. Is the motor in the car?

That's pretty strange.......Considering at one point your fenders mount up to your inner fenders which sit on your frame rails, and you're saying the frame rails are at equal height. The bottom rear dog leg portion of your fenders have two slot's that slide over two studs, not allowing the fender to migrate down very much at all. Is the bottom of the fender at the rear, level with the bottom of the rocker panel?

Is the shock tower perch/reinforcement pushing up on the inner fender? Looking underneath the hood, find the top of the front shock. Look 6-8 inches up from that on the flat surface of the inner fender, is there a bulge or rise there?

OK engines in no front clip on. sure looks to be it the body and not the frame. Theres 2 bolts that connect that front "sub" could they be shimmed?

Are you talking about the K frame. Thats the piece that the lower suspension and engine mounts to. It is held in place to the frame with 4 large bolts. I have never seen or heard of anyone shimming the K frame as this would create side to side variation and the suspension alignment would be drastically affected. Got some pics?

Totally agree.......Along with that, if it was even possible to pull off such a feat, your fixing a symptom and not the problem.

Ok I see, I was talking about the K frame.Im going to figure that its been in a accident and is slightly bent, I will see if I can get some pics and post them.

I'd take it to a good collision shop and let them put it on a frame machine. Being a 'vert, it could be twisted and they'll be able to tell with it up on the rack before you sink any serious time or $$ into it.
