Alternative diff into 55 special

[BU55IK]

Hey all, Does anyone know of a diff that has the same or close to width as the standard rear in 55. also with the 5 0n 5 stud pattern. I'm still trying to track down a donor rear end? Plus being in Oz is making it 10x as hard :Dou:

The best option im left with is to go a custom 9inch. custom axles with the 5 on 5 stud pattern. and close to original length of the stock 55 rear housing. If room permits im going with a disc brake rear while im at it (still on the drawing board at the moment though).

Unfortunately i am in the wrong country trying to find a suitable "drop in" rear end, for the cost of modifiying an alternate diff it only worked out around $300 to go for the ford 9inch.
