If you can't find any, why not make yourself one?
The 25W ones should be ok (not 100% sure cos I don't have my schematics anymore ), but if you can spare a few extra bob, the 50W ones will handle it no dramas.
Although, if you don't have room to mount them properly to the chassis for heatsinking, it starts to get kinda costly, where you will need the 75W ones.
You'll also need the right connector to fit your loom, which wouldn't be hard to find at a wrecker. Or you could hardwire it, or use different connectors.
I would too! Lol.
Alot easier if someone has one lying around!
Just sounded like you were eager to progress with your conversion, so I thought I would let you know in case you couldn't find one.
yeah just trying to get all the bits together first currently pretty busy repairing and doing the upgrades on my brothers VR4 so cant get into mine till thats back on the road.
