Blown the diff !!

[Dino42]

Oops, seems we've bust the diff, at least I assume so ...lost all the drive but at least the speedo still works!
Pulled the engine out, I'll strip it tommorow, assuming it's the diff pin what do you all recommend?

Minispares seem to do 2 options (don't want to fork out for a cross pin)
1. hardened pin, with or without bushed gears.
2. Moly coated pin, but using std. gears.
Which of these is the 'tougher' setup?

It's used as a bit of a road rally car as well as 'normal' so gets a degree of abuse!!

OK cheers guys, you've convinced me - a cross pin diff is on the way, thanks to Rich.
