have clutch brake pedal flywheel clutch pressure plat z bar everthing appears in good order anything I need to double check like bearing size
 
If that center bore is 5-1/8 then it may not work. That bore was introduced in 75. Earlier trannies, including 69, have a pilot bore of 4.35. You should be able to Google that casting number for more info. If you are using the 833 OD trans then a 5-1/8 is the one to use.

found an a body transmisson shifter and linkage last weekend
 
The bellhousing is correct part number and will have the small bearing retainer hole, which is what all small block NON OD 4 speeds came with.
 
If you are going Tranny shopping, I highly recommend a 3.09-1.91-1.39-1.00
This will get your 340 off the line pretty good with 3.23s. The first gear has 16% more torque multiplication, about equal to 2 rear gear sizes. If you get stuck with a 2.66 low, you would need 3.73s to equal the 3.09 x 3.23.
And 3.73s are none too hiway friendly.
The 3.09 low box is not a direct fit, tho, as I think they only come with a Ball & Trunnion output, requiring a replacement mainshaft and tailhousing

If you have an A833 with an overdrive, I call it a 3+1; but everybody else calls it an 833-od. Your 340 will not like this box, unless you put a 2bbl cam into it.The ratios are very far apart, and 340 cams are not revered for their torquiness.lol IMO it is the wrong box for a hi-rpm engine
I've been there,done that; and I ain't going back.
