68-74 100%. 74 onwards have a more rounded shape. dont suppose you want red/white covers do you? i'm making some at the moment lol.
Ta and I want gray/cream.. Ta Ta ..and ta Ta... Think the runner in there is from a 73.. drivers door side runner needs fitting so the one I have in one of the many boxes of bits to be fitted will probably need fettling before it gets stuck to the new metal.. Don't suppose anyone knows the wire diameter of the springs. . so I can order some ferrules to fix the snapped ones.. I'll measure tonight if not. ...edit. .. bout 3.5mm if anyone is interested
My bus was built October 1973 and has that design of seats. On that bus, externally only the sliding door is off an early, the rest of it is late. So its almost not a crossover.
