easy to adjust. Good stability. Helps relieve strain of holding horse's foot.
POA Valve Update Kit - for 134A 1965-73 Chevy, GM, Ford Vehicles [50-2551A]
03 October 2018
Good Replacement
Eliminated sticking POA valve problem. Also I had converted system to R134a and POA valve was for r12. Kind of wish the diameter was bigger where I could have fur the original support clamp back on. Overall ACseems to be working OK.
