If that was the case the armature and/or the field windings would be unique=
...they aren't!!!
Hmmmmmm..

I suspect slightly more windings to cope with slightly more compression.

Its a rainy day at Fox Point so I thought I would look into this to see if =
I can figure out what it is all about.
After an extensive cross check of the component part numbers for the 25521 =
and the 25578 starters I can find no difference between the parts. (There i=
s some argy bargy regarding the brush springs but that seems to be a "red h=
erring"). ;-)
HOWEVER the starter with part number 25578 seems to be exclusively for the =
1963 - '67 Austin -Healey '3000' Conv.=20
The 25521 starter (used on Healeys up to 1963) was still available during t=
his time, it was used on the Humber Super Snipe' the Rover 2000, and the Va=
nden Plas 3 litre 'Princess" but it is NOT specified for the Healey.
There must have been some special requirement of the 25578 starter that was=
exclusive to the later Healey 3000 because creating a unique part was no s=
mall deal.=20
Typically a different part number (disregarding the suffix letter) indicate=
d that the part was not "correctly" interchangeable although as we know any=
Healey starter will fit and work on any Healey..=20
=20
Anyone got any idea what makes the 1963 - '67 Austin -Healey '3000' Conv. s=
tarter different from others?
Note: The suffix letter is a Lucas indication of a change in the manufactur=
ing process for the component and has no influence on the interchangeabilit=
y of the unit, however it can indicate that its component parts may have ch=
anged and interchangeability of parts within the unit should be checked in =
the equipment specifications book.
