I am building from the chassis up and have sourced a pair of Disco axles, mainly so I can get discs all round.  I will be utilising an R380 box and am looking to find out if my prop shafts will transfer from the donor vehicle I have.  (a standard 110 LT77 box).  The main reason for my anguish is I forked out for a scorpion double carden prop in the summer when I put new springs on and as they aint cheep am worried it will not fit my new configuration.  Any advice would be much appreciated.
Thanks.
