I just received my repro Model A chassis and it's not Z'd like I thought it was going to be. It's just a straight rail that tapers from the firewall to the front crossmember with a suicide spring perch and a 10" kickup in back. Now I have a 4" drop tube axle with a behind the axle spring and this thing doesn't look like it's going to sit very low. Am I insane to contemplate whacking and stacking this brand new frame? I'm using traditional steering, (reversed Corvair box to a hoop on the left spindle.) I also made some brackets that hang off the bottom of the frame for my hairpins to mount to. Do I have to wait till the motor is in and the front spring is compressed to drill the holes in the brackets and mount those suckers? Do they go in level when there's wieght on the spring? or can I mount them at a little downward angle so they'll level out when the cars' done? Or does any of this matter? please help a new guy out, thanks.
