Wow I can't believe someone finally picked up that car. It's been for sale forever. I was interested before but the guy selling it just completely turned me off of it.
I'm in the same situation as you. I've got a '71 I'm restoring. For suspension on the cheap I'd suggest some Tokikos ($500 for shocks and springs from an ontariozcar member) (HP's are what I picked up, but Illuminas have the adjustment for dampening, but double the price). I've got Eiback pro kit springs (cheap, good company). I've also ordered a poly bushing master set ($220 I think from PI) and Suspension Techniques sway bar set ($420 from Performance Improvements).
For brakes, the cheapest thing is Toyota 4x4 4 piston calipers and a drilled & slotted rotor with some good pads. For the rear there are a lot of options. Cheapest and easiest I think would be doing a 240sx swap.
BTW, any chance you want to get rid of the front airdam, i`d take it off your hands. let me know
