Gordo2 and I are doing a refresh on my 915 1/2 synchros, dog teeth and slider. We were getting ready for reassembly when one of the needle bearings fell out of the cage. Upon inspection, the seam in the cage had opened up. You'll see in the pics attached that the other cage appears to be cracked but it does not open up like the one with the visible separation. Make sure you check the cages on your needle bearings! It "probably" wouldn't cause an issue since the needle bearings are housed inside first and second gear but we felt better ordering new (OUCH! next day shipping) and knowing the cages are both solid.
