It will probably work okay; just make sure it is in good contact with the head. > Second question : I have a wire that I'm not sure where it goes.

The wires are the same on both the '73 and the '70. There should be small black numbers stamped on the white insulation 1-2 cm back from the crimp connector.

That's a 4th gear switch to switch in the vacuum advance in 4th gear only. You can just ignore the switch and connect the vacuum advance full time. Both transmissions are equally reliable. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
