sierra diff crownwheel and pinion assembly

Hello, any good place to buy (online) a close (around 4) crownwheel and pinion assembly for a Sierra 7" diff?

I have seen raceline offering such an assembly around 500 pounds...anything cheaper?

are you looking for a 4:1 ?

if so one of the standard sierra ones is 3.92 (one of the most common you can get)
I've even got a spare open centre one thats missing the back cover / driveshaft flanges




if you need lower than that (ie. 4, 4.1 etc...) then I think you can only get them as aftermarket ratios for a 7"




(there are some 4.1 / 4.27 ratios for 7.5" diffs in the 2.0 95-98 scorpios)

anything lower than fords own 3.92 is aftermarket for a 7"

Raceline, SBD etc all 450-550 quid though....

3.92 is fine for me.
If you can arrange a shipping to Italy (I need only the crownwheel and pinion, that's much lighter and cheaper to ship) and you ask for a decent price we can make the deal. Please let me know.
