Will Unwin Collar Rails work for Mercedes W639 Rear Seats?

[Jturner1991]

Morning All,

Hoping you could help. I am looking to fit W639 rear double seats into a camper conversion. Does anyone know if the Unwin Collar Rails will be compatible with these seats?

Any help would be appreciated!

Thank you.

I don't know what the collar rails are, Unwin do different systems so a phot or link might be useful.

Not sure if it's of any help but I use the Unwin slide in types into the standard MB rails. So 'possibly' t'other way round would be ok.

Have you considered picking up 2nd hand MB rails off ebay?
