Can't comment one way or the other but in 1974 or thereabouts, I fitted a Mk
2 GT6 wiper motor to my Mk 3 Spitfire. Don't remember there being any prob
with the rack or wheelboxes but it was a long time ago. I left the original
single speed switch in the instrument panel and put the washer plunger with
combi two position switch in the driver's glovebox.
As far as wipe speed is concerned, both are pretty quick on the slow
setting - and meteoric on fast. I've never had such fast wipers on any car
since then.
