I have been Googling the length subject for a while. The only things I have found so far are that Spitbits says to use the 295mm GBH176 while Rimmer says to use 305mm GBH203 in the front. On the rear, Rimmer says to use a 295mm GBH203 which is equivalent to the GBH176.
Unfortunately, these lengths are measured end-to-end while what I can measure for the installed hoses on my car is flat face-to-face. I have to guess at the length of the threaded ends. Regardless, face-to-face, my car's hoses measure about 250mm in the front and 240mm in the rear. If the hoses threads are about 55mm (total) length, then my hoses would be about 305mm front, and 295mm rear which sort of matches Rimmer.
A U.K. vendor (James Paddock) says their kits include 335mm GBH166 for the front and 280mm GBH175 in the rear. As long as the longer front hose doesn't foul anything up front I can see using the 335mm hose. I am thinking the 280mm rear hose is too short. I will discuss this with them next week before deciding what parts to order.
