Slide the seat in with the new column and steering wheel in place and sit in the seat, move it around to where you like it and mount it there I like to move the seat as far as comfortable to the center and as far back as my legs will safely reach the peddles of the car for two reasons, one is moving weight to the passenger side and the other is more arm room from those dang, pesky door bars Think twice, modify once Same thing on the shifter, put it where you like it

need help- bad as I hate to say it!
car finally back from getting a simple 8 point put in.
Mocking up drivetrain: AR engineering motor plate, empty 413 bock with main caps, empty 727 case, stock 72 Duster trans mount bracket and rubber mount for mock up.
Problem 1 : I didn't pull pull old trans out, have mount in with "lip" to the rear as it seems like being toward the front limits access to speedometer drive ( but not cable- we wont be using anyway, so doesn't matter)- plenty of clearance on upper trans bolts for a ratchet wrench or open/box wrench- is this correct? if mounted the other way, engine moves back another 1/2 to 3/4 inch.
Problem 2 : I used a 1 1/4 inch piece of tubing ( thanks Andy ) through the mains, through trans case to help align engine to rear pinion - not going well it seems.
motor plate has to be all the way over against drives side inner fender on frame rail to get real of trans aligned with pinion- im still off to the driver side approx. 1/2 to 3/4 inch. How much play "right to left" on alignment is within good tolerance?
pinion angle ( verticals) I can get, no problem, its the horizontal plane thats giving me grief.
trans to firewall looks square, engine though looks like its angled from front drivers side to rear passenger side.
It "looks like" i need to modify trans mount hanger, move trans toward passenger side and then motor plate to passenger side to everything can be straight side to side , back to front. This would also put me closer to TTI specs on split. right now the difference is 2 inches instead of 2.5 I'm 14 1/16 from pass side frame rail to crank center line. I'm 16 1/16 from drivers frame rail to crank center line.
I'm way, way behind on this car and- frustrated.
Rear housing is square to the car on all measurements. there is no way for me to hit pinion nut to front of crank center unless i move rear of trans. Right now motor place is sitting half on and half off passenger frame rail as we cut off all of the folded up area on that rail.
Install just looks all wrong- goofy, not square. yes, Im aware engine sit to passenger side- just don't want driveshaft/u joint issues etc.
swimming in it in Texas, sheesh!

Any chance you have the motor plate on backwards? The motor plate has the correct amount of offset built into it so it should drop in and be really close side to side.
Here is what mine looks like at the moment.

Plumb bob, stringline, locate the centerline of the chassis. The center line of the drivetrain, from the front of the crank to the pinion, should be parallel to the chassis centerline. If going in on stock mounts, it will be about 1 1/4" to the right. If using motor/mid plates, lowering the engine will help clearances at the bellhousing. Putting a hole in the floor with a removable tunnel to fix clearances and access to bolts will make life easier.
If the results don't match the theory, change the theory.

Center of the driveline should be parallel and offset an equal amount from the chassis centerline, from the front of the engine to the center of the pinion. If the springs are in the car correct, you can measure from inside of spring to the center of the pinion on both sides and that will give you a rough idea of the pinion offset. I.E. if the right side measures 17" and the left side is 19", that's 36" spring to spring with an inch pinion offset to the right. Another method is carefully straightedging across the mounting face of the axle to the pinion. 21" on the right, 23" on the left is a normal 44" wide unit with an inch offset.
I have seen cars with the shafts running back through the car crooked to a minor degree, without any real negative effects, due to the pinion being in the wrong place for whatever reason, BUT I would avoid it if possible, especially in a high power/speed situation.
