Jim,
There are a number of different versions of the gear change on the T5 and the distance 'A 'can be shorter or longer than the 19.5 inches shown. Some boxes out of TVRs have the stick whole lot further forward and I've seen other boxes with an extension out beyond the tail of the gearbox.

yep - like the MT75, Tremec T56, etc there's several aftermarket shifers (and they're pretty easy to fab on those boxes too) but the overall gearbox dimensions are the important ones.

Different applications also have differing input shaft lengths (US V8, TVR, Sierra Cosworth) and I think splines as well? C and D Dimensions are probably the most important to start with though (the main casing).

couldn't find anything with width - I'll search for text instead of tech drawings

Re: T5 gearbox dimensions

There were two generations of T-5 transmissions. All units used from beginning of production in 1982 until mid-1985 were referred to as "non-world class" or NWC. Non-world class versions had all-bronze synchro assemblies and used roller bearings to support the countershaft. In mid-1985, Ford began using the next generation T-5, called the "world class" or WC unit. These had numerous design improvements. First and second synchros were bearing and shaft assemblies rather than solid shafts in the non-world class, and the third and fourth synchro was a steel-reinforced unit with fiber-lined rings. Only fifth gear was still an all-bronze synchro. Both generation Ford T-5s used a 1-1/16-inch 10-spline input shaft diameter and a 28-spline output shaft. The 1983-92 GM T-5s that were coupled to V-8 engines have a 26-spline, 1-1/8-inch input shaft. The GM 4-cylinder and V-6 T-5s used the 3.52 through 4.03 ratios and were 1-inch, 14-spline input shafts. Later model F-Body world-class versions of the GM T-5s used the lower, 2.95 to 1 ratio gearbox and are the most sought-after for GM applications.
Note: 4-cylinder Ford 2.3-liter Turbo units as well as 1993-96 Cobra "Z-Spec" T-5s do not interchange directly, due to a difference in the input shaft bearings. The most important difference between the non-world class and the world-class transmissions is the torque rating. Later is better (or the higher the tag number). For example, 1983-89 Mustang units, both world class and non-world class, were rated at 265-lbs.ft. of torque. The 1990-93 versions were rated at 300-lbs.ft., and the 1993-96 Cobra "Z-Spec" T-5 was rated at 330-lbs.ft.
An identification tag number, which is on one of the mounting bolts on the tail case, can identify all T-5 manual 5-speeds. They all start with prefix 1352, and the next few digits will tell you what the unit came out of originally and what its shift ratio is. You can check any original tag number online at www.5speeds.com. Numbering series starts at 001 and runs as high as about 260. Borg-Warner sold the rights to the T-5 to Tremec in the late 1990s; however, there is no difference between the two manufacturers' production units, other than the name used in the castings.
Ratios depend on tag number, but most are in the 3.35 to 3.97:1 range. There are 2.95:1 units that were used in the late-model Mustangs, Camaros and Firebirds. The 2.3 Turbo Fords used a few units that were 4.06:1. Speedometer drive gears were 6, 7 or 8 teeth, but may have to be changed, depending on engine and rear-end size in the transplant vehicle. Changing of the speedometer gear is a definite requirement when installing a transmission and V-8 unit in a 6-cylinder, and vice versa.
The Ford versions of the T-5 will adapt easily to the earlier Ford three- and four-speed manual bellhousings by an adapter plate which enlarges the metric mounting bosses to 1/2-inch diameter, and adds 3/4-inch in spacing. Installation of a T-5 into an earlier Ford product is fairly easy, because of the bellhousing similarities. You should make sure, however, that the proper flywheel is used, depending on the year of your engine. The 1981 and earlier Ford small-blocks used a 28-ounce imbalance, 157-tooth flywheel. Any of the small-block Fords newer than 1981 used a 50-ounce imbalance, 157-tooth flywheel. These should not be interchanged. Late-model T-5 bellhousings used on earlier Ford V-8 engines will bolt up, but the late-model fulcrum for the fork needs to be replaced with an early-style fulcrum installed on the inside of the housing to align the throw-out bearing fork.
All 1993 and up GM cars with the T-5 used the Ford bellhousing bolt pattern, and not the earlier GM pattern. The 1993 and up GM applications were limited to V-6 Camaros/Firebirds, as the option was not offered in the V-8s. You can identify these transmissions by the 26-spline GM input shaft with a Ford bolt pattern. You should also know that F-Body bellhousings mount the transmission at a 17-degree angle towards the driver, which could cause problems when trying to line up and mount the shifter through the floorboards of other models.

I think that's the one found in the Chimaera, I'll have a look in the garage to confirm, the Tuscan one has the lever further forward and the Cosworth one is at the rear...Quick shift levers are readily available for the Cossy one, not so for the others. They go in a GTE or Coupe chassis no problem and the input shaft is around 1" longer, so using the early SE5 bellhousing allows that 1" for an aluminum adaptor plate unless you want a specific bellhousing. I've got some pics somewhere of the conversion I did on my race car...
