It could either be a 72 dist with an earlier vacuum can, or a whole early dist. 
Either will work, but it would be somewhat interesting to get the VW number 
off the side of the dist if you ever have it out. Then you could tell what it 
originally came with.

If it is only +/- 50 rpm, then this is pretty normal. There is no idle stabilization 
on this FI.

If it cost $50 it was probably used. If it was new he would have paid $200-

You can do it at the generator, you will just expect the voltages to be about 
1/2 V higher there. Make sure to measure it at a high enough RPM that the 
voltage has plateaued (is under regulation.) If it is under 14V there, that's 
slightly low, but not horrible.
