I've started disassembling my 1990 Miata 140k miles, to pull the head and replace the gasket and mill the head.
I'm also taking the opportinity to lighten the car up.

I have the A/C and power steering parts available for sale.

My AC didn't work well, but it was the compressor not working. When the line was opened to reclaim the refrigerant it was still well pressurized.
The car was converted to the R-134a long ago while another family member owned the car.
The compressor is not working but it's good for a core exchange.
$50 for all the A/C parts and brackets.

I removed the power steering pump, bracket, reservoir, and cooler line. Worked great, fluid looks good. I just don't need it.
$50 for the power steering parts, and I'll exchange the PS rack and lines for a manual rack.
