Something is amiss, probably har dto read as you say. 12/76 is HX, probably 12/75 which would mean the BHJ22992B chassis number is spot on. However the BDOY number can't be 359808B. Have a look at the numbers on the end of the skinny VIN tag - should read 8M80LFH3xxxxxJ, the 3xxxxx will be the same number that is on the BODY tag. Should be around 370000 to be right for the chassis number, maybe 369808?
