Hi,

I made a small video on how to replace your CV boots with OEM Mercedes Benz boots,

No stretching required
Easy as hell

Sorry the audio went very slightly out of sync after I edited the video but there's lots of annotations to guide you along you should have no problem at all

This car was a 1975 240D W115
It should work for the W123, W124 ect

Hope this works the whole idea is to encourage ppl to use Mercedes Benz Boots and not have to use a stretch-gun ect... all you need is a hammer and a punch

PS: the camera made me sound all weird LOL thats not how I sounds when I say "Brass Punch"
