Bought a stiffener about one month ago from Mark Ereminas in Oregon City. Just now starting to install and so far the main problem is it's too short by about 1/8 to 1/4 inch. My thought process tells me to install from the rear first because of the need to install the rear shims without the worry of horizontal alignment under stress if the front is already attached (i.e the need to adjust the shims to accomodate the rear cross bar). So far I tried to jack the car at left center body but made no difference. One thought is the front flat iron plate that attaches to the sterring box bolts bottoms out against the rear of the wheel well which may be the reason why its too short. Just some thoughts begging an experienced response. I have read most all the posts on this issue and I'll keep you posted with my (lack of) progress and pictures.
