Does anyone know if the roof gaskets from a 355 are interchangeable to the 348. I would love to replace mine but the 348 ones on sale from eurospares and other usual suspects are ridiculously priced. 355 gaskets for front rear and sides seem to be price is far more palatable and readily available spares so really hoping they fit. If anyone could also advise the part numbers required for the front and rear of the roof as its not very clear on the parts diagram. Thanks
