I recently picked up a set of what we’re supposed to be BJ60 axles with 4.11 gears, a lunchbox in the front and spool in the back. Unfortunately I ordered them off of a Facebook ad and had them delivered, without ever physically seeing them. I’ve now pulled them apart only to find that they are both 3.7 gearing and both are open. I looked for indication to prove that they are at least 60 series axles but the info I’ve found to date is inconclusive. The Center section of the front is stamped 41111-60. Hoping to put them under my 77’ 40 but now don’t know how to proceed. Any ideas?
