Yes, he does. He did the conversion in my 300TE to R134, and it's perfect, though I am sure he will repair existing systems if you prefer. Here is his info: Greg Wehde, Sports & Vintage Car, 1271 Route 12A, Plainfield, NH. (603) 675-2623. Give him a call, and tell him I sent you, (he'll know me by my MB's). You won't be disapponted!
