In case you're in any doubt, gcp is the Genuine Classic Parts division of Volvo so if they haven't got it, nobody has!
Except maybe something a dealer bought in 1982 and might be listed as NOS now. That's how i managed to find the oil cooler for mine (and then it had to come from Sweden!
) but i have to re-engineer the aftermarket nipple to fit it.
It's all part of classic car ownership, you either spend years waiting for the OE part to come up at an autojumble or you find a way round it.
Bearing in mind, with something like a gas spring that deteriorates over time anyway, even a NOS item might prove useless in 2 months time.
Then you're back to square one so need to find an alternative solution, either an aftermarket direct fit solution or modifying aftermarket parts to correspond with the original.
