I'm humbly asking for the retro rides collective for their acquired knowledge of all things Fiat and possibly Lancia in this thread as I've googled and yahooed part numbers, many car makes/models car specs and all sorts on this until the cows have come home every night for a few weeks now, also popped into my friendly auto factors who couldn't solve this riddle.
The back story:
In my quest for updating/uprating the braking on the rear of my Cinquecento (second hand calipers, new seals, new handbrake cable and pads works out cheaper than new back plates, cylinders, shoes, and handbrake brackets for the drum set up) I purchased a set of used rear calipers and brackets and gubbins from a fiat uno turbo, all sold unseen so no lynching required as it was worth a chance at the price. All seemed good, it all bolts up lovely with no faffing, BUT I went to purchase some new seals to refurb the calipers so measuring them seemed the best way forward just to make sure I bought the correct seals. The first caliper was all good, bar the aforementioned seals, standard Uno turbo caliper with 30mm piston, super smashing great, just thought I'd measure the other just to be sure, and ... oh... 28mm piston... um... remeasure, remeasure um still 28mm... okay, so i scraped off a ton on paint on both. one is marked Girling 30 (I'm guessing this is the piston size 30mm) and the other reads Girling 28/30... Ah... so...
A technical questioned type thread is no good without pics so here's the offending items:
The odd 28/30mm caliper
The 'normal' 30mm caliper
The Question:
I can get another Uno Turbo caliper, but would like to find out what this elusive 28/30 caliper with 28mm piston is from, in the hope I can sell it and regain some of my outlay on another caliper. so far I *think* it may be from a Lancia Y10 4x4 or Turbo my hunch on this is that some of this model came with rear disks and use the same brake pads, okay so not enough evidence for a complete conviction but can anyone confirm that the Lancia Y10 used a Girling caliper with 28mm pistons or offer another suggestion???
A beer at the gathering for anyone who can confirm my suspicions or point me in the right direction.

38mm piston calipers would over brake the rear of the cinq.
