7610

Can any one help with what the correct ratio is for the ZF 4wd DROP BOX fitted to a series 2 7610. ID plate missing from existing unit . Need to aquire a replacement box but believe there is more than one ratio on these boxes depending on which 10 series it is fitted. I have been offered 0.905...
