Chris - I've logbooked a couple of stock cars for NASA SU, here's a few things they've had problems with at tech:
Shoulder harness angle - some cars have the seat crammed right up against the rear bulkhead with harnesses at a bad angle, or three bar adjuster contacting the seat. Access is poor, no way to fix at the track.
Shoulder harness anchor point - it is OK to redirect the shoulder harnesses with a properly located tube behind the seat, down into the chassis and tied to a hard point on the frame. A problem is that this space may be shared with the battery, or open to the LR wheel well. Damage from tire debris and/or contamination from the battery is a fail.
Fuel cell bladder age documentation - NASA has a firm 5yr max rule, and FIA FT3. I suggest keeping a copy of the the bladder sales receipt with the logbook, and fill out this form for tech:

NASA requires a right side net or a head restraint seat. The flimsy Kirkey head support thing does not meet the rule for a restraint - it is a support, useful only for napping in the car. Tech needs to see a restraint.
Brake lights, exit time, cutoff switch kills a running motor, HD padding, the other usual stuff. This is the checklist I use for the logbook, I advise doing a self check as soon as you get the car:

For SCCA, I suggest contacting your regional chief scrutineer, and the TA2 series director - you may have an issue here if they tell you different things. I had an issue trying to get a customers Cobra replica into SCCA Vintage - the series director was looking for car count, so was OK with vintage prep, but the regional chief took a hard line on prep, insisting on a full GCR cage, etc since it was not an original.
