M&H (Year One) 66 V8 engine forward harness HU270A

That will work for up to 74 I believe. I would be onto it for our 67 but exchange and shipping puts it outta site. Also ours is elec ign with 70 + charging system so I believe yours would need mods?(not sure tho) Google the part #. About as good an oem style engine harness you could get.
Good luck. Trades?? Lol

I already looked it up, it is the non electronic ignition version... too bad about the shipping.. the exchange rate we could probably overcome, but every time I ship something to the great white north, it ends up being a losing proposition.
