but wouldn't use an a6 with r134 myself

I too have used the Sanden Kit, and have one in stock that I intended to install, but am still using the A6 and 134a in the 4840...found a leak at the rear head, (large 0 - ring), repaired, and this will be the 9th year of the combo...

Just posting this for those who may need to convert the freon, and wonder if the old A6 will handle it...it does..., quietly, and smoothly...like they are known to run...

Good Luck,

CF
