can't find stock shock details

[Doris]

Hi all,
been offered some new front shocks for bus, the only details I have from them is part no. 211.413.031.8 VW COFAP. 285mm closed in and 420mm fully extended.

don't know if thats a repo manufactureres part no. or if that's a Genuine VW part no and where do I find the stock specifications to make sure its the right set?
p.s. my bus was made on 27 Jan 69.

Thanks in advance - Rob & Doris!
