Yet again VW dealer efficiencies are apparent. No help at all! Need some up to date part numbers for the longer rear seat mushroom bolts as the 703####### numbers are now no longer available. Is there another option for installing the seats? Tried a few eBay types but they are either so expensive I'd need to sell the van to buy them, or the short ones. Seems its all going knockers-up with my LWB.
