72CudaRacer, NHRA reunion website lists Bruce Bachelder 317-216-4869 or Pat Cvengros 626-914-4761 for any tech questions. I haven't seen tech crawl under cars to check the stickers on trans shields but where one is visible (on your balancer) they might get picky. They made me change a Teflon oil pressure line to a braided line a couple of years ago before I could run. The guy behind me in tech had the same Teflon line and they passed his. Tech is kinda hit and miss I guess. See ya there.
