Canada No-spin for Eaton Rearends and installation manual

[68chevyfuelie]

Up for sale one No-Spin locker made by the Detroit Corporation. It was originally in a 1969 Chevy 3/4 ton longbox stepper. It has been on a shelf for the last 20 years waiting for someone to give it a good loving home. If memory serves correctly there was either a No-Spin or a Detroit option on the SPID, and the installation/sales brochure in the glovebox of this vehicle. I tried doing some research last night, and to the best of my knowledge from what others have posted on here, the No-Spin will fit either a HO52 or a HO72. Apparently HO52 was 3/4 ton only, and HO72 was 1 ton only, the only difference being the brakes. This locker has COARSE spline side gears, the one picture sort of shows the side gears. If anybody has any more information on these units, I do not want to misrepresent what I am selling. Asking $350 before shipping for the No-Spin and the brochure. First "I'll take it" posted in the thread gets it.
