Default diff viscous fluid?

Hi

I've a rear VLSD diff from a Sierra cosworth 4x4, but it's old, and works like an open diff....So I want to change the Viscous silicone...
I don't have the money to send it to England an get a professional rebuilt(I'm a student ). So I want to try to rebuilt it at home as I only have 120-130bhp on my sierra and not need a very tight diff

could you recomend me a website where I can buy this?

could be useful the silicone that RC cars use on their diffs?
thanks

I like how it goes, is good
stock diff:

LSD with RC diff silicone 500.000cps:

But now, the diff is out the car, because I did some in a bad way...and probably a bolt inside the diff broke, and the case crashed...I have to dismount it in a weekend and check what happened

I dismounted it, cleaned all discs, and remount using this silicone.


I don't know which is the correct viscosity...I only tried with 500.000 CPS

I bought it on this shop of my country 3 bottles, used 2 and a half

how do you adjust the side bearing preload?also i have used 100000 two bottles and one 300000 with good results,don't tight very much the viscous because the planet gears are not too strong!so don't use up to 300000 silicone oil
