Mk3 Anni rear calipers

[GTIANNIVERSARY16V]

Looks like I need new calipers. A few months ago my hand brake became slack, I replaced the rear bearings, rear discs and pads, hit handbrake levers with a hammer and gave the calipers a good lubrication..... Everything was fine until last night, I got home and could hear a familiar snap crackle and pop sound coming from the rear wheel, it was very very hot and had the all familiar weird friction smell.
 I have found a website but I can't figure out which ones on the page I need. As nobody bothers to explain the difference. Ones 70 quid the others 40.

Which ones do I need?

Go on the Euro Car Parts website and enter your Reg Number then look at the different calipers. Nothing special requires Bud

Ive done that mate, but they have two versions aswell. And it costs 300 for the pair according to my calculations :s

The difference seems to be the width.
I never knew there were two versions...so I suggest you measure the width of your exusting rear calipers and order the same ones again.
