Barrie, I can vouch for the universal gators from car builder. they are pence compared to the Morgan options which are fragile beyond belief. Don't know if you re-lubed the rack when you changed the last one out but I have found that the rack's don't seem to have any real lubrication other than some protective surface greasing by Quaife. Guess Morgan just fit them but don't apply lubricant. Needs to be a slumping grease that won't just move aside after the rack and pinion have been through it a few times, Slumping grease will move back and resettle maintaining constant lubrication. If you want you can have a look on my posts and about a year ago I did a write up on rack maintenance. A tell-tale will be, does any graphite looking lube come out when removing the gator, a fair amount per side actually. My plus 4 is a 2010 model and I have changed out two MMC gators both on the left side. Second one even had a micro defect on one outer bellow fin which leaked from the off! turned the defect to the top to prevent leakage and ran it for two years until it failed...... yep, split an internal fin just as the previous two had!

Main reason I replied though! got side tracked.....Yes I can vouch that the Windermere ferry is as flat as a pancake both sides of the lake. When there last time I asked them if there was a change in height due to weather conditions effecting the height of the water and they said in was negligible and shouldn't change things enough to cause a problem with low cars.
