Thanks Bob!
I still need to put it to use and see how it performs. I suspect it will have a slight creep since it's a well used cylinder and it also has a slightly bent rod. If this becomes a problem with regular use, I will make a new rod and repack the cylinder. It should make good as new.
One thing I've noticed on my Branson, is with my mower and tiller, I always need to open the top link almost to the max length. Since I built the hydraulic top link according to the dimensions of the original one, I might have no room to tilt (ie: box blade) back. Which can be solved with a longer rod. No big deal.
