Hi Mark.  I used a 1500 spacer.  No idea what size the saloon spacer is.  I don't have a barn full of donor cars like you

Fair question. The reason I switched to a high torque starter is for cold starting.  My cold start routine is to crank the engine until the oil light goes out, then give it some gas and a little choke and fire it up.  I do this simply to preserve the engine because I cannot abide the rattle of a triumph engine running with no oil pressure for a second or two at cold start. My engine has a higher than standard compression ratio.  The Lucas starter used to struggle a bit in this scenario.  It was probably on its way out anyway, so a switch to a cheap high-torque starter was the way to go for me.

Can't remember. I applied power to the solenoid and measured the fullest extent of the pinion, then measured the distance through the starter mounting hole from the engine back-plate to the ring gear, and then calculated how thick the spacer needed to be to make sure the the pinion would be fully meshed into the ring gear.

It fits with no skimming, and will start the engine, but when I measured the throw on the pinion and the distance to the ring gear, it showed that the pinion was only meshing about 5-6 mm into the ring gear.  A sure route to early failure of one or both components.    I cannot remember how much I got removed from the spacer but it was enough to ensure that the pinion would be fully meshed into the ring gear.

Yup, that's the one.
