Looking around to see what else I can accomplish while waiting on parts.
I thought it would be appropriate to post these pictures for anyone planning out a similar swap. Fitted my existing spark plug wires to check for fit. I believe these were stock size, but I couldn't swear to it as they came (almost new) on the engine when I bought it. I have plenty of extra for looms so I think that any wires made for the FC RX7 should work.
