I have a 1979 4x4. Long story short we pulled the front wheel apart to replace the bearings. When we took the bolts out of the locking hub we noticed that they had all been broken off at the ends. I found similar bolts but not exact. I was just wondering if anyone knew the bolt size that was supposed to be here. Thanks

Which bolts? The small ones that attach the outer cover to the hub body or the larger ones that bolt the hub body to the wheel hub?

They are the 6 bolts that hold the locking mechanism for the 4 wheel drive in place.

The bolts that hold the dial & cap to the hub body on a later 17-spline Aisin hub are M6x1.00x15, I would expect your earlier 24-spline hubs to use the same bolt.

The part number is 94029549. I found that in the master parts list on this website.

Since your truck is a LUV that should be a GM part number, not an Isuzu part number. A helpful local GM dealer might at least provide the specs but may not be able to order.
Found this after a quick Google of the part number: https://www.ebay.ca/itm/10-CHEVROLET-LU ... 2397292125
