This is a plate that I have made a number of times to fix draw bar problems such as bolt holes broken out.
If you make 2 of these then you can put your draw bar any where you want.
These will let you put 2 to 3 bolts in each plate.
I just use 3/4" bolts where the pins in the reg. plates are.
Sorry about some of the pics. but I can not scan a page as long as these plates are.
