Hello Keith; I can help you a little. Attached is a file with Laycock serial
numbers and models for the A-Type overdrive. Also is a calculation of the
different ratios. The following responses are from them.
Q If from other than Healey what are they from
28 / 1502 / 002187 Rover 60, 75, 90
22 / 61711 / 028383 ** ????? factory rebuilt
28 / 1292 / 7137 AH 100
28 / 1327 / 1134 Standard Vanguard
28 / 1447 / 005267 AH 100-6
28 / 1447 / 12566 AH 100-6
28 / 1463 / 002155 Humber Hawk
Q What is the result of using the 22% ** unit
The Laycock overdrive enables the choice of an extra-high overall gear ratio
for high speed cruising at lower rpm, thus saving fuel, at the cost of less
torque.
Q Are they all compatible with Healey
Regarding compatibility, I do not know. You will have to get that from a
Laycock overdrive expert. :-)
