sierra brakes

[rich]

hi all, my donor car was a "h" plate sierra with the twin cam 8 valve engine.
When i stripped it i made the mistake of throwing the discs and pads in the scrap bin, went to euro car parts today to pick a new set up, apparently my year of sierra was on the changeover and theres 3 different sizes for the front discs and pads aarrrghhh!!!
Iv ordered the biggest and praying they will fit.

On the plus side just found out today my diff is geared to a 4:1 ratio, apparently they are as rare as rocking horse poo and quite sought after
