Was digging through some images and found this....
its a Tremec 3550 that has had the front of the rear shifter housing machined flat down to the rail, and a 1 piece cover fitted over the mid shift position and the newly machined rear shifter housing front part, looks like it fits against the front of the remainder of the rear shift box and then under the red shifter base, sealing all 3 parts, you can see a glint of gold under the position of the rear bolt holding the red shifter base down.

guess it raises the shifter base(red bit) an inconsequential amount or the bush in the offset lever below is shimmed up slightly with a washer under the rim of its Top hat

seemingly fits without crossmember cut out and removal.
But still needs top of tunnel cut out in front of it, because of the amount of case and cover above the input shaft centre line is still pretty large i.e too wide for standard tunnel side to side.

seems to work on a 3550 because the shift rail is tight to the top of the tail shaft tunnel,
won't work on a T5 because the shift rail is 1 inch or more higher then the tail shaft tunnel i.e way higher than the shift rail position shown below. i.e it would want to pass right through the stand-out part of the cross member hump, the lowest part of the pressed section. Take that extra inch out of the equation, I'd guess the 3550 shift rail would pass under.

presume this is a very early Keisler modified box....

uses a single rail shifter into the mid box that has a 3 rail shifting mechanism by the look of things... similar to some of the current bigger tremec boxes...i.e that mid position box is going to have a few components in it linking the 2 styles of shift rail, so it can't be hacked off.... but the front section of the red shifter base has been, i think

Do you have a 3550 to install? Because the 3550 Family (3550, TKO, TKOII, TKO500, TKO600) have ben replaced by the TKX.

I have an unmodified TKO600 in my car and can share the ins and outs if anyone is interested.
 

no i just found the picture when sorting stuff the other week and thought it might be of interest. someone went to the effort of making the box fit the car rather than the car fit the box at some point over the last 20 years, and during that time I've messed about with a T5 and never got round to fitting it...hence i have pictures off emails from mopar people, or downloaded from messageboards, that i must have felt were useful at some point, all stored in a folder i forgot about, showing things they felt were a good solution... this was one of them
 
That was the standard A-Body offering from Keisler. As I understand it, while it was better, the u-joint angles still weren't optimal.
