Nice motors. 4 layer flatwounds work great here. I would suggest using a different basket if you went 10" again since the stock basket only has a 6.5" spider landing. Unless you willing to take the time to mill out a riser that adapts to 7 or 8".
I could rebuild these for about 130ea. Would come with a 4 layer flatwound, dcr of your choice, spiders of your choice, and a DD cone assembally, cap of your choice.
Bump OP. good luck. Built a pair of these about 4 mo ago. Strong motors.
