65 Barracuda, slant six, 833 4 speed. My shifter isnt centered and just barely contacts the forward edge of the hole in the floor hump in 1st gear. Its too far forward to install the boot without badly pinching it. I have the correct shifter(forget the #) and mounting plate # 2298, which I think is correct and shift rods from Brewers. Motor and trans mount line up nicely with K frame and cross member. Shift rods are good, except reverse is at the end of its adjustment.
Does anyone have any ideas about this, or another mounting plate?
 
What are the chances that you have the wrong adapter plate or the wrong screws in the adapter plate that has allowed the entire shifter to be in the wrong place or has over-rotated it?

The mounting plate has round holes with round chamfers for the screws- theres no range of movement. I’ll check Brewers and ShifterDoc tomorrow for part #s.
OldIron, the engine snd trans mounts are tired, but theres no longitudinal deflection.
 
You didn't say, is your car a factory 4 speed? If the hump was added later maybe it was welded too far back.

Here are a couple pictures from Jamie's book. Great reference book as he documents just about everything related to the A833.

I'm interested because it took me a long time to collect all the parts to convert my 1964 /6 to a 4 speed. I guess I'll wait until the trans is in before I weld the hump in.
The floor shift cars were converted as the cars moved down the assembly line. The hole was cut (torched?) in and hump welded on the line. Poor guy probably only had a minute to do each step and was good for +/- 1/2"
I could just hear it now, "Oh no, here comes another #@*%+! 4 speed car!"
 
The cut out area of my floor does look like it was cut with a torch in a hurry. I dont know how it would make a difference, but this car was originally V8, 4speed. I bought it as a gutted roller and installed a /6 and 65 A body B&T 833 using a later OD bellhousing. I havent heard of any length differences in bellhousings or floor hump locations between V8 and /6 cars. I could, but am hesitant to remove the carpet and relocate the shifter hole and brackets for the shift pattern trim plate. Maybe modify the holes in the shifter mounting plate, or replace it w one that angles the shifter a bit rearward?

OK, this may be a dumb question, but is the shifter itself adjusted correctly? There's an L shaped 1/8 inch diameter tool for this, or you can use a drill bit or bolt of the same diameter (if it will fit between the shifter and the trans tunnel). Pop the tool in, and then and only then adjust shift rod length.

If you've already done this, just disregard the above.
 
Yep. Done it- shifts real nice. I’ve been having thoughts about re adjusting it on an imaginary point that centers the shifter in the hole.
