Hi Scott!
I haven't seen too many photos of the HAF B52+ cockpit on the Internet however I have to say that it is almost identical to the ones posted above which depict the cockpit of a Block50/52 aircraft. Two very small points of interest:
1. On the left side, just below the eyebrow warning lights, the HAF Vipers have the drag chute switch which you can see on the pic below noted with the green circle. On the same location, the RF switch related to the radar transmissions exists on non-HAF Vipers.

2. On the bottom of the left auxiliary console, the HMCS (helmet mounted cueing system) panel exists alongside with the RF switch.

(both original photos can be found of the HAF website)
Usually you can find more photos on the HAF website (on their majority, they are external):

Good luck with your build!
