Well, been awhile and long overdue.... Finally found a schrader valve to fit, now the shop is ordering a shizload of caps since none they have fit as the inside diameter is larger than the old. Sorry I didnt get pics of the new valve yet but got dark out and only have a crappy cell pic to show.... Got it vac'd down to 28 for 2 hours and a 1 hour leakdown test of 0 so it stayed at 28....yah me ! The rent of the pump and manifold ran $279 but got that back when returned, the schrader valve ran me $10 and the 134a/PAG100 oil ran $85 for 32oz/oil as I needed the fill kit... heres some pics, enjoy.
