A/C installation advice on a R107

This is a repost from over in the SL forum. Sorry if anyone gets snagged by the duplicate.

After a year of telling myself I could do without it, I've decided to repair the air conditioning on my 77 450SL. The problem has been professionally diagnosed as an internal leak in the compressor - apparently the PO replaced it with a rebuilt one that simply hasn't held up.

Anyway, after my shop quoted me $1100, I decided that there's no good reason not to do the job myself. The manual states that you need to remove the radiator, etc to get at the compressor. I have access to a lift, and being lazy, I'd rather avoid pulling the radiator if I can.

Has anyone done this job from underneath, and is it easy enough to be worth doing that way? Any pitfalls to watch for?

Thanks in advance.
