Exactly how much refrigerant?

Okay,
I looked here there and EVERY-blessed-WHERE but I can't find out how many oz of refrigerant it takes to fill my Euro system. (and no, it has no rear cooler) My mechanic says his M635 was 1400 grams which just over 42 oz, I think.

2 questions:
1) Has your ac system been converted to r134 or are you running r12?
2) Not related but I noticed you have an Ireland Engineering exhaust. What has your experience been with it?

EdwasRed,
My a/c sys is running r12 for the simple expedient that it passed 2 fifteen minute vacuum tests with ZERO leakage and this meant that instead of a roughly $350.00 rebuild of my existing compressor, we just partially filled the system. To your second question; I love the exhaust note, it's just the right combination of throaty and civilized. I can not speak for any other I.E. exhaust install but happily I wasn't doing it myself. Apparently the pipes were not in the correct positions where they join to the engine and it required my installer to use his shops' pipe bender to configure the I.E. pipes correctly. I can't imagine trying to do this yourself without professional pipe bending tools. Has anyone else installed an I.E. stainless system?

I imagine there would be a difference between R12 and R134a setups and then also between the models with a single evaporator and the models with the extra 'fridge' in the back?
Would there be a difference between setups on for instance he M30Bxx, M88/3 and S38B35 given the same refrigerant and amount of evaporators?

Thanks Pod!
Stoffie, I don't know what differences (if any) there are and that's why I'm asking the brain trust. The only dumb question is the one you don't ask, yes? My original stickers are long gone, since I re-did the hood insulation and I never got replacements. I probably should see to that. Who had those by the way?

Mine never had any stickers since I got the car, wondering the same for my M635CSi as I had to take out the condensor so pretty much at a loss as you are on how much to fill it with once it's all back together.

Stoffie?
Doug Park, (the gentleman working on Grace) had an M635 and his was 1400grams, so I think you can use that figure. That's 47.333 liquid ozs.
