Nice looking car JohnMat, I like the heritage dash with that as well.
I have the roll hoop headrests GregA10, it was suggested to me that a rear end shunt would smash the back of your skull in without them, that could be right? It was also suggested that I should wear a crash helmet rather than have headrests for the same reason, then someone else said that with seat belts and a crash helmet but no HANS device, you could break your neck........ It seems that whatever you do something bad could happen. I have headrests and no crash helmet (mostly) and that seems to work well, unless the weather is really bad when a helmet and visor would be nice but takes up a lot of room when you don't want it on. There is no perfect answer.
