I need a measurement on 68-70

I need some help. I'm building a tube chassis car and I need a measurement from the front of the firewall to the front of the front frame rails on a 68-70. Doesn't have to be to the 1/32nd, just close. Thanks so much!

38 1/4" from the flat part of the firewall (where the heater line to go through)
