1st Gen Locking Hub Compatibility

[Cricket]

Question for the 1st Gen guys.

What years will the locking hubs be compatible with a 1970 blazer Dana 44 front?

Mike (3onthetree) may need manual hub lockouts and I had a set of spicers from a 1980 3/4 ton. As far as I can tell the lockouts are compatible up until 1976.

Anyone know for sure?

provided it is an internal hub then 69-91 Dana 44s and GM 10bolts all use the same lock out.

67-on internals will all work. I put my '69 lockouts on the '82 disc knuckles I swapped onto my Blazer.
