I’m in Canada so here it says $250 Canadian. I looked and a better alternative is a wifi sender for $50 that you can use your phone to open garage doors.
Is this the set that goes to the black box with 1.25B Glow and 2.0L Main? Do you sell these? I have a 1991 HDJ81 from Japan that also runs the the 3 wire FL but I can use this and combine with the 90982-08266 that you make.
When I did mine 6 years ago I missed a step on assembly because it was missing in the instructions. I can’t remember anymore but I called them and climbed under and reassembled and has been great.
Werewolf makes portal boxes that attach to your existing axles. I think it's a brilliant approach as you can mount them on ifs suspension as well as solid axles. Great example is the Land Cruiser 200 series they did.
Look at Ironman America, they sell them for under $200 and they have sale now.
