Universal hand pattern control changer install for excavators and backhoes

Hello.

I have a Cat 225blc cat excavator.

I am most familiar with backhoe control. But other operators are familiar with old cat style controls.



Does someone make a hand pattern control changer that is a universal install on most machines? Specifically my 225blc?



I changed the hoses around on the old cat 225blc to accomadate my backhoe style.

But i need it to be able to be changed like my cat 320c machine.....which has a factor setup to change the pattern.



also. i need to install one on some old backhoes. specifically a john deer 310c.



thanks so much!
