I just wanted to say thanks for the extremely helpful guide. We have had our Plus4 for 10 weeks (our first Morgan after 10 years in MX5s) - my wife was finding the seat uncomfortable and I could hardly move the drivers seat back and forward it was so stiff on the sliders. Following your guide and the other helpful suggestions I cut some tapered wooden wedges 30mm front to 7mm rear for both seats and refitted with these. Seats are more comfortable and drivers seat slides easily thanks to the extra hole suggested. Took me best part of a day start to finish including trimming the overlong bolts from the underside at the end.
Great to get some confidence in working on the car and achieve a more comfortable seat in the process.,,
Anyway, just wanted to say thanks.
