Mystery Loader for 4020

I got a great deal on a loader for a new to me 4020 out of a tractor salvage yard. It has 148 decals on it but the bucket cylinders are missing and mount under the arms instead of over the top of the arms like every other 148 loader I have ever seen.
Also, the way it attaches is unique. It doesn't attach to the engine frame but instead goes from the rear axle then to the front 4 bolts by grill. I have searched all over and only found one picture online that matches and it had no identification though it was mounted on a 4020.
I need to buy bucket cylinders for this but have no idea what length and stroke I need. They should be shorter than the normal 148 since the mounts are closer from the underside than if they were on top like normal. I measured from the mount to the upper limit stop and it was about 24" so I'm thinking that would be collapsed length.
Any ideas on what this loader is? Source for replacement cylinders?

Thank you! The cylinders are missing but
after your response, I looked online and it
appears the 46 has a square brace and the
46A has a round tube like mine so I think
mine is a 46A. At least now I can get the
cylinders.
Thank you again. You are a life saver.
 
The loader you have pics of is a 46A. You can use cylinders from a 47 as well. It looks like someone has changed the front end so you might have to do some fabricating work. I have a 46A on a 3020 that we use. Tom
 
The very first 46A loaders had the square brace instead of the round. On a 46 the cylinders for the bucket are very small and mount on the same pins as the lift cylinders. Forgot to ad that bucket cylinders from a 36A will work as well. I have some extras here but do not want to sell them as I am always buying and selling loaders and sometimes find nice trip bucket loaders and convert them over. Tom
 
If you have the time, I would appreciate some measurements collapsed and fully extended for the bucket cylinders. So far I have found numerous sources for rebuild kits but no complete cylinders including Deere itself.
I'll stomp through the scrap yard again if the rain holds off and see if I can find something but most of the loaders were picked apart. Guess I should have looked closer but this was buried in the weeds and he quoted me $700 for what I thought was a 148 on the decal and told them to dig it out and put it on my gooseneck. Thought I stole it. LOL Came with a 7' bucket and a homemade bale spike so still isn't too bad if I can make it work.
 
Just measured my 46a. With the cylinder tilted back the length is 25 1/2 inches center to center of pin holes. Fully extended it is 42 inches center to center of holes. You may be able to use a longer cylinder and just have stops on the bucket for it to get against. Right now mine has the bale spear on that has no stop so the measurement above is completly extended. Hope this helps. Tom

IMHO longer cylinders attached to original mounting locations wouldn't let bucket rotate correctly especially the roll(curl) back function.
