Have purchased several of these for 12V conversions and they work great!

It is exactly wanted to use on my 1955 Panhead. I will purschase a new battery for it, since the current one does not work with the box.

I have a 1957 panhead that I used the battery extension kit on. It worked perfect and looks stock now under my seat and that's exactly what I wanted.

Fits OK. Some pieces couldn't be used, but it's working well.

Perfect fit for my 1951 panhead. Dopped right on in. As Scotty from Star Trek would say-"it fits like a glove".

The fit was good and the quality was fine. The only problem I found with the unit was the pedal does tend to keep popping out, however I think that can be fixed pretty easy.
