More on shopping for a side link cylinder...
The cylinder should be stout enough to compare with the size of the machine and the 3PH...A side link only requires a 4"-5" stroke...
The issue is finding a cylinder that when extended 50% of the stroke and (modified with the correct ends) measures (pin to pin) the same as the OEM static lifting rod...
Most peeps that install T&T move the adjustable lift rod from the right side to the left and install the hydraulic tilt cylinder on the right side especially if the remote QD's are on the right side...but what ever works best for hose plumbing is prudent...
If you are moderately handy and can weld it is not a difficult thing to make/fabricate your own custom side link....there are an untold number of threads here where others have done it...it's not something that takes any special talent or machining tools etc...There is lots of information and threads here on TBN describing the procedure (with pictures and everything)...!
IMO, For anyone that uses their 3PH for anything other than pulling a mower/cutter...hydraulic top and tilt is the single most beneficial modification an owner can make to their tractor...it's like upgrading from a shovel and a wheelbarrow to a back hoe and a dump truck when it comes to making it easy making adjustments...it also greatly reduces the the learning curve on most implements because it makes it so easy to make minor adjustments without having to get off the tractor...
