For those of you who would like to install a 722.6 transmission into your late model 107 or 126 with electric speedometer drive

I have made an external tone wheel for the 722.6 transmission and have a compatible VRS sensor to drive the 126 electric speedometer. I am selling these at the development cost they are priced at $350.00 for the wheel and sensor. You will need to fabricate your own sensor bracket, I can provide a drawing but it really needs to be fit in place. I have 3 available at the moment. Last picture is and older style with nuts. The ones available have threaded holes see first two pictures. They are fabricated using 4140 steel heat treated to 145 KSI, which is the equivalent of a grade 10.9 bolt. The stock 107/126 bolts are grade 8.8
