I do still have to climb in the engine bay and mark for my O2 sensor bungs, drop the exhaust and weld them on.

I had intended on leaving the A/C compressor and power steering pump hooked up and set to the side in the engine bay.... but realized it is just so much easier to leave them attached to the engine.

I have a vacuum pump and will recharge the A/C system myself.

Anyways, took a couple of Alleve and I am done for the day!!

Hey Jared,

what clutch kit and flywheel did you end up using?

thanks

Coolant shows up tomorrow and I have to top off the PS fluid.

I jumped the start signal wire to the battery and she cranks over nice!!

Jared,

did you have to do any persuading to the down pipe connection or do they just line but design?

I have a set of these for someone else's project. On the outside, they look decent, Interior needs a lot of grinding, as no effort was made in construction to make them actually flow, or fit the pipes up. I am going to test fit them before cleaning them up.

This method is know to work perfectly, but it takes time and patience to cut, fit and weld. Also, must use SS MIG wire, with matching gas to get rust proof welds. I need to go back and look, but think I used 308L and argon.
