truth guard cranks

Question

I need 5 of these cranks
30744A,40754B,30744B, 30818B, 40754A
I wrote these down that were on the cranks, but was told these were just the inventory number of the parts. The letter behind each of these numbers, was located on the short arm of the crank

Hello there. This might be the 39-032 Dual-Arm Operator, but make sure the dimensions match what we show below. Let me know if any of the arm lengths are off. For new covers and handles, see the 39-114L and 39-107 sold separately.
