    So, I installed the A/C components back into the beater. When I got the car, everything was missing aside from the evaporator housing. The engine that's in there is a 72, so I had to use the steel lower bracket instead of the aluminum style. It seems now that my negative spring ring cable seems a bit too short.

    At first I thought the 71 cable might be a little longer because of the steel bracket is far thinner where the cable connects. But I looked the cable up in the M&H catalog and the 70 and 71 cables are the same number. Now Im questioning if I have it routed correctly. At worst, I was going to use a steel spacer between the lower AC bracket and cable to take up the space lost.

    I was hoping someone could post a picture of the negative cable routing or a picture of that general area so I can make sure I have the A/C lines routed correctly as well

    Who knows if this is correct Jason. I played heck getting the OEM positve in (it was off of a Riv) where the battery is on the drivers side. See what you think. Doesnt the book show that in detail? The orange one I made, but redid the original which went to a front cylinder head mounting bolt just below the AC bracket mount. Definitely want a solid BLOCK ground! ws

    That's for the pictures Bill. With the AC compressor, AC muffler and lines installed, there's a whole lot going on in that small area. Not alot of real estate for all that population! What I had to do to get the negative cable to fit was thread it OVER the AC muffler and onto the bracket.. That was the only way for that factory spring ring cable to fit.

    I didnt realize you were going the OEM route! With me making my own I did get it to run under the AC muffler. Cant wait to do the ATF lines! ws
