Agree with Jerry. The bottom line is just seeing if there is pressure. You can "T" off and install an aftermarket gauge to reflect actual pressure. That's if you think that you will never know if you have too high of a pressure. I would not worry about that really.
Anyway be sure you know about what pressure a 235 should be. Idle and driving.
Aftermarket gauge should fit snugly in ashtray. Open ashtray and look straight at it. Line will flex enough.
A blue light digital gauge could be seen thru the speaker grille and be hidden when off.
Right is right, even if everyone is against it, and wrong is wrong, even if everyone is for it. - William Penn
