Richard,
I'm new to Morgans and am sort of perplexed. My car does not have sliding seats. It has wooden platforms that sit between the steel members with a bladder on the top of the wood for a cushion. Seems rather crude but effective although there is no way to adjust the seat position. I've looked at both steel members and have found no numbers. We are talking the passenger side aren't we?
Mine's on the driver's (right looking from the rear of the car) side on the cross-member behind the seat.
