Voltage regulator: Standard Motor Products (SMP) VR124. It's electronic and works very well. It will save the alternator blowing out if the regulator fails. They cost around $24. The black wire goes to ground and the other two connect to the leads for the stock regulator. This is a replacement for Bosch units used in early 1970s BMWs, VW bus and a few other German cars. It provides a steady 14.1 volts at the battery. Don't leave home without it! (Ray Costa)

Voltage regulator: WELLS VR650 at AutoZone, $29. It's for a 1973 BMW 2002. (Ross Kowalski)

From Keith Pedersen:

"My 12V Chang uses a bulb 12V H4, but it isn't the one with three tabs on the base (on the shelf in all auto parts stores). I found a bulb 12V H4 but with a P45T base. It's 60/55 watt and works great, fits right in the headlight. NAPA part 6260A"


From David Olesen:

"For those who have the original turn indicator light socket with the 12V 10/5 watt bulbs, the 7225 (21/4 watt) European bulb will work fine... after filing off the upper post. It will still stay in with one post as long as the fit is snug. All four bulbs should be the same, so replace them all. It's also nice to have the brighter turn indicator for those blind auto drivers. They can be found on the shelf at Checker for $2.50 and should also be at Autozone, but may need to be a special order."

From Trevor Bos:

NAPA part numbers:

Tail lamp sockets LS6538 will allow indexed bulbs (aka 1157) to be used.

I've made up replacement plug wires using the following numbers, a significant improvement on the originals. The NGK resistor covers are better sealed and the wire doesn't leak voltage like the originals. (You can actually pull them off with the engine running, shock free.) The only difference in appearance is the black jacket and the extra seal on the NGK covers.

Resistor covers 8381 (NGK LZFH)
Ignition wire 734803 (38-40 inches required per set)
Ignition wire terminal 727003
Ignition wire nipple 727303
