2 questions on transmission spark cotrol system

[Steve D.]

Okay,
my 70 350/300 has most of the system missing. I have located all the parts to be purchased except for 2. The hard tube. If I cannot locate one maybe I can have one bent. What is the tube thickness? 1/4 inch?
I also the the relay that is part of the system. Any suggestions on where to locate either or both for purchase?

I think you will have to bend the tube, but one of the board participants posted about this, with a measured diagram in the past. Perhaps that member is willing to make one for you. Try SEARCH
