Man, I've scoured the internet and e-trailer is the only place I can find with a parking option but I want to get 6 lug hubs and spindles. I seem to come up with a #42 spindle and then miscellaneous hub set ups. I didn't find a source for the cables for the parking brakes. E-trailer has some poor reviews but I guess that is due to the volume of sales. I had thought of using old spindles off of an early fj40 drum brake but I think it would take more work than its worth. I had also thought of using mini truck drums and backing plates but I like the idea of having electric brakes on a trailer too.. This will all be for a heavy M416 build, extended tongue and heavier frame.
