Perhaps you could try taking a brake pad out and matching it up to a brake pad catalog?
Wouldn't be definate, but might help?

stock as stanza struts, unless someone changed em on their stanza that i got it off!

theyve definately got girlock calipers if that helps

see pic and tell me what they are

i dont think i ever actually measured the disc i was just going by what i was told

soon to get 240k struts, would that improve situation?, i was going to put U12 pintara discs on (with hilux 4 spots) so it could change again though couldnt it?

not sure, i was going to get a pair and see what they were like.

trying to decide what would be best for the conversion, i beleive the 240k would be better height, brake and clearance wise?
