In grinding those welds, I've been going through flap disks at a phenominal rate. I bought a fancy-pants one at Lowe's, but I don't get the impression that it lasted any longer than the Harbor Freight disks (which are less than half as much). I've tried everything from 40 to 120 grit. I prefer the 40's for faster grinding. One nice thing: The cheap 4 1/2" angle grinder I bought at HF is one tough little booger. It's been getting flogged for months now, and still going strong (knock on wood).
Next step: Touch-up welding, some grinding and POR-15 (when it comes).
After that: Repaint/recoat floorpan/firewall and re-attach the subframe. From there on, it gets expensive for awhile. I'll need:
- Body/Radiator Support Bushings/Hardware
- Ball Joints
- Coil Springs
- Tie-rod Ends
- Steering Box (3rd Gen IROC Z)
- Disk Brake Conversion
I was pretty surprised at how cheap the steering box will be. Less than $200 from a number of vendors. From what I understand, the IROC-Z steering upgrade is one of the simplest but most effective upgrades you can do on these first-gen cars.
