cv boots

[subman60]

Back in High School in the 70s I drove VWs. They use to make split cv boots that could be rivited or bolted on. Seemed to work well on my VWs and I drove them hard. Has anyone had any experinces using them on MBs and are they even available? After watching a video of how top do the one piece I'm not sure I have the expertice for that job. Also it is building up alot of rpm before it will shift 1st to 2nd and 2nd to 3rd. I can let up alittle on the gas then give it more and it will shift at lower rpm. Does this sound like a vac problem or something else? Ifsomething else how do I go about diagnosing it?

Thanks,
Mark
