Well if you do break 'um the repops are well made.
I worked for Montgomery Ward long ago and they sold quality parts.Monroe made the shocks, and Firestone made their MW brand tires.We had a big parts counter and carried brakes,exhaust,ignition parts, filters, etc. A good company to work for.
All I can say is you are doing fine work.Better than new.That little car never had it so good.The battery cable run would be fine either way.
