Love, love, LOVE the rack and pinion steering. He used the existing holes from the old steering box and idler arm for his R &P gear brackets.
What we don't see is his measurements, taken while the engine was still in place. That's how it's done.
I like the fact that R&P offers more room for exhaust on the LH side and more room for starter motor maintenance on the RH side.
The rear end is a beast. It's going to need a Panhard bar. Nice job! - Dave
