Comments: A really nice looking cap for your master clutch reservoir can be found on the 2000 Chevy Cavalier. It fits perfect and it has specs written on it "use DOT 3 or better". Fits the 1972 Spitfire and maybe the TR7/8.

Comments: The only difference between the TR7 and TR8 differentials is the gear ratio and brake cylinder.
“I'm overhauling the differential in the '8, and replacing the bearings and seals and one leaking axle seal while I am at it. Here is a cross reference of the Timken numbers (bearings only, no seal info):

Drive shaft - conversion
Application: TR7/8
Triumph Part #:
Other Part #’s:
Other Vehicles: Range Rover Classic, Triumph TR6, Jaguar XJ6
References:
Comments: Most TR7/8 drive shafts came with either u-joints or CV joints on both ends or one u-joint and one CV joint. Some Canadian (and Australian) TR7’s may came with dual u-joint shafts. All TR8’s were equipped with dual CV joints.
Work Arounds:
Conversion possibilities:
Range Rover Classic, short wheelbase driveshaft is almost a perfect fit. The rear mounting flange bolt holes may need to be opened up for bolt alignment with the differential input flange.
TR6 drive shaft can be adapted to fit the wedge. The length needs to be adjusted. The rear mounting flange bolt holes may need to be opened up for bolt alignment with the differential input flange.
Drive Shaft from Jaguar XJ6 LWB. Needs to be shortened by about 1 1/2".

Comments: The factory parts manual doesn’t list the Canadian (and possibly Australian) TR7 5spd drive shaft with both front and rear u-joints. Later TR7 and TR8 had two CV joints. A number of venders describe GUJ115 as a GUJ101 with the addition of a zerk grease nipple.

“The following gears were available from the factory:
Output shaft worm gear (the rear cover needs to be removed to access this gear – top picture)
Colour # teeth Part #
White 7 TKC1273
Black 8 TKC1274
Pinion gears (these stick out the side of the transmission and attach to the speedometer cable – bottom picture)
Colour # teeth Part #
Orange 20 219001
Green 21 219002
Red 22 219003 or 219003A
Black 23 219004
Blue 24 219005
White 25 219006
Assuming stock tyre sizes (185/70-13) the following applies to vehicles as delivered from the factory:
TR7 (3.9 rear axle) : Pinion: black (23) Output shaft: white (7)
TR8 (3.08 rear axle): Pinion: red (22) Output shaft: black (8)
The rest of what follows hasn't been verified mathematically by me, but back in June 1997 there was a protracted e-mail discussion with the main contributors being:
Fred Smith:
“Other Gear options that apparently work:
3.45 rear axle | Pinion : Green (21) Output shaft: White (7)
3.45 rear axle | Pinion : Blue (24) Output shaft: Black (8)
3.08 rear axle | Pinion : Orange (20) Output shaft: White (7)
3.9 rear axle | Pinion : White (25) Output shaft: Black (8)”
Mike Jeffreys: (Note Mikes term "driven gear" is same as my use of "pinion gear")
“My 'rule of thumbs' are:
1) that each tooth on a driven gear gives a 5% change
2) when you go from a 3.9:1 to 3.45:1 axle this is about a 10% change
3) when you go from 3.45:1 to 3.08:1 axle this is about a 10% change
4) when you go from 3.08:1 to 2.85:1 axle this is about a 5% change
So,
1) a standard TR8 gearbox driven gear has 22 teeth,
2) a TR8 gearbox driven gear with a 3.45 axle should have 24 teeth,
3) a TR8 gearbox driven gear with a 2.85 axle should have 21 teeth,
4) a TR7 gearbox driven gear with a 3.9 axle should have 23 teeth,
5) a TR7 gearbox driven gear with a 3.45 axle should have 21 teeth,
6) a TR7 gearbox driven gear with a 3.08 axle should have 19 teeth but the lowest value available is 20, so 5% under-reads, just like my TR7V8-)
7) a TR7 gearbox driven gear with a 3.9 axle could use 22 teeth (seems to be closer to reality in my TR716VSprint)
8) a TR8 gearbox driven gear with a 3.9 axle should have 26 teeth (have to use 25).”
Note also that the reason we can mix and match our speedometer gears is that the speedometers themselves are calibrated to be directly replaceable whether they be for TR8 or the various different ones offered in TR7's over the years.....This is why we can also mix and match speedometers without affecting the accuracy of readings.” - Mark Elbers
Transmission – 4 spd

Other Vehicles: Herald/Spitfire/GT6
References:
Comments: Interchangeable with Herald/Spitfire/GT6, but with different gears. J type overdrive from the Spitfire can also be added to TR7 with a shortened drive shaft and additions to the electrical system. J type overdrives were also used in Fords and Volvos of the same period.
Transmission – 5 spd
Application: TR7/8 - 1979-81
Triumph Part #:
Other Part #’s:
Other Vehicles: Rover SD1
References:
Comments: TR7, TR8 and V8 Rover SD1 transmissions interchange, but TR7 requires different speedometer gears due to rear axle ratio. TR7 gear change is longer than the TR8 or SD1. The TR7 bellhousing is different from the Rover V8 cars and not interchangeable. Later (1981) transmissions were upgraded with better syncros and different 5th gear ratios.
Transmission Borg Warner T5 conversion
Application: TR8
Triumph Part #:
Other Part #’s:
Other Vehicles: 1990’s GM F-body Chevy Camaro/Pontiac Firebird, 5.0 Mustang.
References:
Comments: The Borg Warner T5 from a 1990’s GM F-body Chevy Camaro or Pontiac Firebird is a Rover V8 bolt up using the early 1960’s BOP (Buick Oldsmobile Pontiac) belhousing used on the Buick 215. Clutch and gear shift position may need to be modified along with the rear transmission mount. Custom belhousings are also available to swap in the Ford version of the T5 which uses different belhousing bolt pattern from the GM.
