Yeah, I had to ask the same thing. I thought someone had switched handles on my 57 Bigbolt.
But to stay correct, leave the key lock on the passenger side and slide across the seat. However this is a task in my LCF. The gearshift and park brake handle is in the way, when you are 70 and weigh 185 lbs.
Also try sitting under that big steering wheel, and the seat is all way back.
Folks must have been smaller back in them thar days.
