    I need some advise on my front end. My 65 Skylark, 462ci w/nitrous (old motor), has stock front suspension, 300v8 springs, summit 90/10, manual steering gear from a '71, front drums and spindles have been replaced with discs from a '72 Cutlass, I just popped the ball joints & tie rods and swapped the whole spindles, I'm still using the origional "A" arms. Now here's the issue; when I run the car down the track the left front wheel seems to "hang" kinda funny, top of tire is "toed in" pretty far, enough to notice the angle (from watching the viedo), and visually really noticeable when turning off onto the return road. Car 60fts. low 1.50's and ran low 10's, pictures of the car launching, you can see the lt. front wheel off the ground about a foot, with the bad angle, Why??? I've replaced the ball joints a couple years back, never did a front end alignment, car went straight down the track. I've been told that I should put an adjustable travel limiter on the upper control arms, weld in a nut and a threaded rod to do this, and an alignment, should solve this problem. I'm about to put in MOROSO trick front springs, and Hal adj. front shocks, and should address this problem. Also, with the car jacked up, and supported by jack stands on the frame rails, both front wheels have a top of the wheel "toed in" angle.
    This was/ is with a big block in, new big block will make a ton more power, should be a low 9 sec. ride, I'd like it to be a straight safe ride.
    Thanks for the advice, Gary G.

    Gary,

    All of the A body cars have the same prob. It has to do with the spindle height and A-arm geometery. Since this isn't a road racerg ou should be fine.

    The best option to fix the geometery is to use 70-81 F body spindles and aftermarket tubular control arms. That is what most G machine guys do.

    Hope this helps.
