Would have to disassemble to measure accurately Steve and there is already one in bits on axle stands and engine hoist.I dont think any Manufacturers details are available on that model I can refer to.

what about this bill 312mm eye to eye bargain i reckon http://www.ebay.co.uk/itm/LOOK-BMW-S100 ... 1e71ebd85e

ive been wondering about one of these for my 3tj,modern shock,all the bells and whistles i just didnt know how long they were,ive just measured my spare 09 13s r6 shock(albeit roughly) and its 290mm eye to eye give or take a couple of mm.might be a good up grade-might buy it myself.

Thanks for links Steve,was trying to keep the non intergral remote if possible to maintain some sort of authenticity.
