I think some engines didn't have a Z, but rather had an A for anticlockwise, like his engine.  My clockwise rotation SR2 has no suffix letter

Apologies for any confusion but the Z made an appearance when Lister became Lister Petter. The SR range was before the LP merger. Looking at your pictures your SR is Anti clockwise rotation ( the style of bellh ousing is the dead giveaway)

OP, your still going to need that spacer between the bell housing and starter motor I mentioned in my previous post.

I used a magic marker to count the teeth of the original ..(was quite rusted)
Count was 10 ... im sure of it. The one delivered was 11 ... so I started a return ... im sure its not the right one.

Ok, im to the point that the roatation and tooth count is correct ...
I need the spacer ... but will the original studs be the correct length or will they need replaced with different lengths?

I already broke one stud off removing the original starter.

I can see the image:

https://www.ebay.co.uk/sch/i.html?_from=R40&_trksid=p2380057.m570.l1313&_nkw=133970436456&_sacat=0

Yes from the picture, that looks to be what to be what your looking for.

However, be aware of the following:

1) Ensure the direction of rotation of the starter motor is correct, as Lister's definition of direction of rotation has caught many people over the years (NOTE! If your engine serial number has SR2A, the A indicates anti clockwise rotation)

2), You will need a spacer to go between the starter motor and bell housing, like so:

      https://www.ebay.co.uk/itm/265239226729?hash=item3dc17d6969:g:evoAAOSwdjVg-bIX

 This is for the HA series that use the Lucas CA45 starter motor, but the general shape is very similar to the SR engine.

3), Finaly confirm that the number of teeth on the bendix is correct.

That set up looks similar to mine but mine is not a governed engine as for a generator. Mine is a variable speed engine in a dumpy truck. With mine I can move that lever one way, let it go and it goes back to the idle position. Then if I grab that lever and pull it out and away from the block then the lever goes into the 'cold start position for easier starting in the cold.
So long as that lever can move freely then it should be ok to do a start up once you have your starter mounted and wired. Being a generator it may well want to go to full throttle first up to start generatin g power and not come back to a lesser speed until it realises that either no power is being used or under load. Maybe a good idea to be ready to shut it down quick if needed so take note of that lever and what it does when you start it up.
How are you going to remove the broken stud from the starter motor? I have drilled many out always very careful to find centre then drill out to being undersize to the thread. Then I use a very smal pin punch to collapse the last of the thread and it will wind out. Heat also helps along with some penetrating fluid of your choice. Heating and then squirting the pentrating fluid onto it helps it get drawn into the thread to aid in freeing it up.

Still tryingto find a rig spacer ....

The starter I last received seems correct ... just sitting too deep into flywheel

Did you buy the spacer from Ebay? If not maybe make your own from a solid piece of alloy and shape it to suit.

The number plate in the photo shows the engine as being an anti clockwise SR2 built in 1973. The letter A denotes the rotation. Lister always quote rotation as looking at flywheel.
