I got an indication the seat may not be in exactly the right location. The good news is that it is probably close enough to proceed. Once I get the column installed, I will review the feel. This is where I have problems with the interior. I am used to solids which are easy to measure. Seats are soft, irregular, and hard to measure.
I held a straight edge over the center row of buttons on the seat bottom. Dropping a plumb bob from the straight edge in two locations yielded the green line which, in the photo, is lower on the left than on the right. The other green line is parallel to the center line.
Then I sat in the seat while holding a steering wheel with the plumb bob through the center hole. Surprise, surprise. The bob consistently hit close to the period after the H. I settled on putting the red line just to the side of the H, parallel to the center line of the car.
Carrying the new column center line up the toe board showed that the lower column mount hole needed to move outboard 2-1/4".
I also removed the pockets where the brake pedal and the clutch pedal came through the floor. Look at all the crud these pockets held, now accumulated on the floor.
After cutting out the lower mount hole and moving it outboard, a filler was cut to fill the gaping hole. Everything is tacked for now in case I have to move them later.
I am not sure what the floor was like on the car these seats came out of, but it must have been a real mountain range. The right rear support is a real monolith. After measuring, it was a apparent an inch had to go. After cutting it, the tab needed to go. It originally mounted the wiring harness. That's OK because it needs to be rerouted anyway. After welding, the seat fit a lot better. It still needs a lot of work before mounting, but at least I know the driver's seat will not have to move because of the passenger seat.
Well, the 2009 family vacation is in the history books. Flew to Phoenix via Dallas. Put over 1800 miles on the rental car over 8 days. We visited with friends that moved to Gilbert years ago. We don't get to see them often, so it was great to spend a day visiting with them and their family. Saw the Grand Canyon, Petrified Forest/Painted Desert, Meteor Crater, Flagstaff, Sedona, and met a real interesting WW II war hero.
So, back on the 41. To be honest, I was a bit apprehensive about the interior. All my previous cars had basically stock interiors. The exception was my drag car. Of course, the drag car only needed to be functional for limited periods of time. If I get the driver's seat, steering wheel, and pedals wrong, it will mean misery for miles on these OK roads. If I get the passenger seat wrong, it will be worse!
Anyway, with the seat in the mid position of all adjustments, I centered the seat and marked the mounting positions. After marking them, I removed the seat. It was then that I realized the holes would have gone into the floor braced. I moved them forward about 3/4". The green squares are the original marks and the red X's are the locations to be drilled.
Three of the four mounts rest on the floor. The left front will need some spacers. For now, I stacked washers. A quick test sit and it feels good.
I decided to test the passenger seat before proceeding. It ended up sitting high and leaning toward the center of the car.
