I crashed my 94 325i bmw. The collision occurred to the passenger side front. The damage isn't that bad so I'm going to attempt to fix it myself. However, I fear that where to the front part of the frame attaches to the rad support may be swayed over from the collision.

I have a Bentley manual, but it doesn't give any frame measuring information. If anyone can help me get this information or direct me some place that can, I would appreciate your help.

 

Typically unless you have experience with autobody, just straighten things out until everything fits back together.

If you need to install a fender it's perfectly acceptable to have to shim some areas so they line up with the next panel (bumper, lights, airdam, door, etc).

Since it's front end damage you should take it in for an alignment after the body work is done. $50 for an alignment doesn't even come close to what you pay for one tire, so driving it long enough to figure out from tire wear that your car is out of alignment, that math just doesn't add up.

The "big boys" these days use a frame machine that has lasers under the car that scan it and locate critical features like bolt holes, then compare them to the factory specified locations that are loaded into the machine's hard drive. From that point, they use spreaders/cables/winches/hammers to move things around and back into position.

 

Thank for your help. Very interesting.

The reason why I'm concerned about the frame alignment is because Where the headlight attaches to the inner fender, that hole is about 1 inch away from the hole on the headlight housing when the headlight housing is attached to the rad support.

I'm not sure if the frame alignment is causing the hole on the inner fender to be off or if it's the damage to the inner fender. I don't want to remove the inner fender and weld a new one on and still be misaligned because of the frame.

If I could get the measuring points and specs, I could see if the frame was bent or not and let a bodyshop handle it if it is.
