69 Dart GT Conv. 340-6pak

Been a while since I flipped thru...Great work and some great choices! I like the idea of the mech oil psi gauge and the elec. Looks like you might be able to turn the "T" back counter clockwise to help with the firewall "issue"?? If so could you get a "locknut" to thread onto the "T" to lock into position??
Great work!
