I decided to put hydraulic brakes from Great Plains on. So i will have to modify the axles and wheel pant attach plate (L01-13). Also will be putting 5.00-5 tires. Put axle from GP on that has a plate with (4) 1/4" bolt pattern. Drilled (4) 1/4" holes in landing gear. Made a L03-13 from .063 thick 6061-T6 aluminium. this is needed so the larger tires, GP brakes and wider wheel pants will fit. The L01-13 is 13" long and 2 1/2" wide with (2) 90 degree bends in center section. It will mount in the same place as the original piece. The axle spacer is 1 7/8". Also need to gring edge of caliper so it will not rub on tire.
