You can make one if you like. Find something a rod that fits the pilot bearing (or close to it) then use electrical tape to make up the difference. use the tape to make up the difference till it's the same as the friction disk.
If you eyeball it and you're off, they are right and it will never go in. You'll be bench pressing it on the ground all day
(unless you have a hoist)
I did mine on the ground 2 times and one for the hoist.
get'in tired of it.
