Questions about C4 suspension in 57

[slyfry]

I have put a Flat Out C4 kit in the front of my 57 and fabbing my own mounts to put the C4 suspension in the rear. While mocking things up I came across a couple of things I have questions about that those experienced with this setup might be able to answer.

In the front the stock Corvette rack and pinion has fluid lines the go straight up towards the motor and if left as is the motor must be mounted a little higher to clear these lines. Flat Out sells a rack and pinion with these lines relocated solving that problem but creating another in cost, at $425 plus shipping both ways (core charge) we're almost $700. What would be the drawback of just using a T-bird rack and pinion ($150 local) and saving a bunch of money?

In the rear making my own mounts copying Flat Out's design I see 2 problem that appear in mock up. What are they using for bump stops (limit travel), I hope not using the shock as a travel limiter. And it appear that the toe bars will hit the frame before full compression travel so what are they doing to solve this, are you having to notch the frame?

After reading all the build threads here I guess I need to get to work and start one of my own, but first I need to find a better hosting service as Photobucket is just too much of a pain in the ass to use, Any suggestions there?

Thanks for any help!
