Steering rack

[willf]

Hi guys, pas fluid has been pissing out of the rack gaiters and having looked at other people's posts on the same thing i'm assuming a seal has gone in the rack somewhere and i need a new one, well 2nd hand one anyway. What i want to know is if the racks are all the same lock to lock etc, i know there appear to be 2 types of rack - facelift and pre facelift i think but can someone confirm what i need? Car is a 1990 Is. Cheers!
