At work we have a lush koken double ended socket, and it winds on reverse thread like. then you can undo them sweet as.
Apparently we are not allowed to sell it.
Tis mean for staff use though
what would you be getting for that $600? Like all wiring?
reverse light, tacho + other gauges etc?
If its just the basic wiring to get it running that seems a little steep imo
If your certain it fits M series its a M to W50.
Has the same bolt spacing for the box as that one in the pic, its just cos its got that yuck Holden bell over it.
