Diff input flange question!

[moelk]

Im about to change my R200 for a Subaru R180 sti diff.

I need to change my input flange on the sti diff for an input flange from a datsun R180 but i dont have one of those. But does someone know if the R200 input flange will fit  on the sti diff?

They have different part numbers.  Doubtful.  I've never had an R180 though.

Thanks!!

Most likely it will not fit, damn!

Hunting begins for a R180 input flange i guess.  

Will be hard to find.
