| List, 
Just to confirm the MGA ratio in my TF, I did the following: 
1. Jacked l/r wheel off garage floor, r/r left on floor to prevent rotation, 
gearbox in neutral. 
2. Rotated l/r wheel 10 turns while counting driveshaft bolts as they went by. 
Counted 86. 
3. Divided driveshaft bolts by 4 to get driveshaft revs. 86/4=21.5 
4. Divided driveshaft revs by wheel reves. 21.5/10=2.15 
5. Multiplied by 2. 2.15x2=4.3 (the standard MGA diff ratio. 
Apologies to all those who "knew this already", but in searching the web to 
confirm my recollection of this procedure, I found everything from "it can't be 
done" to "divide by 2" and even " take the cover off the diff and count teeth".
