I'm a pretty large lad myself and like you guys decided to restore a 12cab Ford CMP as my first truck. My helper, my father, also a bigger fella.
Here is what I did;
-reduced the seat cushion to maximize room
-eliminated the wooden spacers under the seat mounts
-tried to drive wearing work boots, a no go.
-switched to running shoes
-drove barefoot but not for long as the engine heat cooked my little piggies
-finally figured a way to clutch as little as possible while utilizing the right toes and heel combo to facilitate fuel delivery and braking capabilities as needed.
In other words, if I had no arms I'd be great at painting with my feet... Practice and more practice.
