After more thought, here's what the next half a dozen part purchases will be:
A used vertex magneto with tach drive or HEI "faux" magneto
A dash panel/gauges
A cloth-wrapped wiring kit
The carbs on the 6X2 need to rebuilt or replaced, then synced and linked
I'll let the market dictate which items I acquire first, while allocating a monthly budget towards the list.
It's my hope to have all parts necessary by mid-summer.
