Factory 4 speed owners-looking for a measurement

[pontiac guy]

Here are pics of all 3 common T5 lengths next to each other with a tape measure for scale.

As for the tilted Firebird T5. To the best of my knowledge that was done for clearance for linkage and later hydraulics. Tipping a left shifter farther left only exacerbates the situation. The 4 spd bellhousing is unique and I don't remember it being rotated. It is also dual bolt pattern. SBC and BOP. My 82 isn't here at the house nor is my spare bell for it. I'll get a pic when I go to my other building. Maybe tomorrow. The F body T5 housing is entirely different as far as I know. Chevy only. I've never compared the 2 oddly enough.

The 82 F bodies did not have tilted bell housing. The issue was the tunnel was designed for a left offset shifter. The T5 has a centered shifter. It was easier to tilt it to the left to get the center shifter to line up with the existing hole in the tunnel. The 82 4 speeds and 83 5 speeds still had a mechanical clutch linkage with a z bar. The 84-up were hydraulic.

This is where my T5 came through the floor. It's a mustang tailhousing. You can see the location for the factory auto cable and the mount for the auto console.

That looks like the rear bracket for the automatic shifter. The front of the console on the Chevrolets mounts to the front of the shifter. Your T5 shifter is back far enough that it would be into the console.
Like I said previously, the Tremec 3550/TKO transmission has their standard rear shifter the same distance from the front flange as Mustang T5 as the Tremec was 3550/TKO was designed as a bolt in replacement for the Mustang T5.

Here is an above shot of the stock shifter placement in relation to the dash.

Can I get a dimension from the front seat bolts to the back of the cutout in the hump? I want to locate my hump correctly when I do the carpet swap.

Is that a plastic trim piece that goes over the floor hump and below the boot to cover the carpet edges at the cut out?

It'll cover edge of the cut out which outlines the more rasied part of the hump (hope I explaned it clear enough). The older carpets had a pre-cut pattern in the jute pad to cut the hole

The transmission that I want to install is a new Tremec TKO, not a T5. Here are some photos of how the shifter setup looks on it. Going by the measurements that I've taken, comparing a stock type Saginaw 4 speed with the correct '78-'81 A body shifter on it, the shifter location on the Tremec is about 2"-2 1/2" further to the rear, and roughly 1" further to the left of the centerline of the transmission than the stock setup. I'm going to call the supplier on Monday, to see if anything can be done, but I just want to make sure that my measurements are correct, by comparing with other owners who have a factory 4 speed setup.

So yes, there's a plastic trim piece I'm missing. Insert swear word here. Thanks. Do you know the dimenson? I'm trying to finish my conversion and I want it as close to "factory" as possible

The factory hump and plastic bezel will most likely not clear a centered shifter.
