Looking for lockers for the front and rear 1978 Ford D60 axles. Prefer constant lock in the rear(full spool, 4.88 gearing), but would consider something like a Lok-Rite or such. In the front(using thick gear, so 4.11 and lower carrier) I would very much prefer something that engages/disengages on its own to keep from grenading my U-joints. I won't mind paying to have it shipped,, considering the price and condition.
There is no carrier break for Dana 60 fronts. They all use the same offset spacing & it should be a 35 spline. The rear is the one with the break. I'd look into getting a bigger rear axle. The small 30 or 16 spline axles don't hold up very good locked up.
