Front suspension options
Gerst Suspensions is another option

Still in the way too expensive category but, thanks, I didn't know about them.
What year A-body?
What are you intentions for the car? What specific type off perfomance and to what realistic level that you will actually utulize?
Is header clearance the main standout goal?
Standard '67-'72 A-body. In particular, my '68 Cuda. I have no problem cutting, welding, and modifying anything on this car. True daily driver. Just looking for affordable options for a car that would get blasted down the 1/8 or 1/4 once or twice a year, do a lot of car shows and cruises, and maybe even try an auto x at some point. No, I'm not looking for whats best to do drag racing or auto x but something that could handle both just like the stock suspension can yet have better ground clearance and easier to work on.
We all know than a standard A-body with a SB sucks header-wise with horrible ground clearance, almost or completely captured starters, and clearance issues with P/S gearbox and steering linkage. Plus, gearboxes are no match for modern R&P steering. Then there is the weight of all that old torsion bar/gearbox stuff.
I've even been looking at possibly adapting the front suspension from something else to work. One I have been interested in is the '03-'04 Ford Crown Vic front suspension. It is used by a lot of the custom truck/hot rod guys and has proven pretty reliable, has huge brakes, shares the Mopar 4.5" bolt pattern, has power R&P steering all mounted on an aluminum crossmember, and can be had fairly cheap from just about any junkyard. For an A-body it would need to be shortened some but that isn't as hard to do as some think.
Eh, like I said, looking for options and just spitballing right now.
