Those nice people at http://www.sgs-engineering.com/ agreed we could return the gas struts and the new ones are on order. Rather than order specific T25 struts, we measured the dimensions of the old struts and took note of the force rating (this is printed on the side of the struts) and ordered struts that matched. The guy from SGS was surprised as we appeared to want the gas struts that they normally supply for the T2 Bay Devon, rather than the T25. So either the gas struts we have aren't the original ones supplied by Devon, or Devon used some T2 ones, which is interesting (check out http://en.wikipedia.org/wiki/Volkswagen_Transporter if you need to brush up on your VW bus history). We also realized we needed different force ratings for the horizontal and vertical struts (we have one vertical strut at the front, and two struts at the back that cross over as you can see below).
We have set aside a full day this weekend to the van, so hopefully the new struts will arrive by then. If not, well we will have plenty of other stuff inside to be getting on with. We have a rust patch to fix inside, and Nick wants to have a look at the electrics and take out the old fridge.
