I popped into the local Landrover (on my way back from the engineers to drop off my manifold to be re drilled tapped and threaded 101 manifold ...Grrr!!! ) main dealers today on the off chance they may have some manifold bolts (downpipe to manifold - 101 stylie). Equiped with my 101 parts manual part number we soon learned it was of little use to the catalogues they used.
Eventually the very helpful chap came up with a part number for the bolt 3/8 UNC 1 1/2" incase I managed to get it at another Rover dealers. He went on to explain various elements of the part number... for instance 5 reflected UNC... then another number reflected the length of the bolt.
To say I was stunned that Landrover had actually applied some logic to some part numbers was an understatement.
Ended up at the local nut and bolt specialists. Could anyone in the know give any more insight into decrypting numbers?
