Hey 1854Sailor, I’m in a similar situation. My 1966 Plus 4 left the factory with bucket seats, but has had bench seats for long before I bought it 7 yrs ago. I’m not the tallest guy in the world (5’11”) but it feels like I’m practically on the floor. And there’s zero lateral support during spirited driving. Didn’t get the Mog for lazy trips to the grocer.
I eventually picked up a set of period appropriate bucket seats from the Ecklers at Morgan Spares. I haven’t installed them yet. Was hoping to get a period set of seat rails to mount them on. Bought a cheap set of 60’s Sunbeam seat rails- looked perfect but they don’t fit. The spring for the lever release juts out the side. I need an alternative mount.
The Holden seats look very period appropriate. Have you thought about how to mount them? I could make wooden mounts, but I liked the idea of being able to adjust it a bit.
