i say

- disc brake front end, 120Y struts and castor arms are a bolt in fit, and use the dual system 180B master cylinder.

- 14in RX4 steelies, painted black.

- DUMP THE BITCH INTO THE WEEDS

- one 45DCOE weber, 30/70 cam and a good exhaust. use pre-pollution 120Y headers.

- celica 5spd gearbox.

- oh, and the nice paint bit. that always helps. like that new commodore red.

all up, incl a good paint job, i reckon you could get away with a $5k build.
