Expert Reply:

Yes, but all of the the couplers for 2" wide channels and 2" hitch balls use a different bolt spacing than the 2-1/4" spacing your Shelby 5128 coupler uses.

However you can still use a 2" ball coupler like # DL13835 which has a 3" bolt spacing, but you'll just need to drill holes as needed.

If drilling holes is a no-no for you, then you'll need to stick with your existing coupler, or replace it with another 1-7/8" coupler like # CT-2001-Z which uses the same 2-1/4" spacing as your current coupler.

You can certainly go ahead and re use the existing 2 bolts, provided they are in good condition. The fish wire method shown in the video works too, but it is also very common to just use the two bolts like your old Atwood actuator. Personally I would…

Yes, you can remove your weld-on coupler and install a new bolt-on coupler that fits a 2 inch ball. There is just a few things you need to do to before and when installing. You need to know what channel size and the weight capacity you will need for…

I can certainly point you in the right direction. Switching from hydraulic drum brakes over to EOH disc brakes is basically going to require a full conversion kit. It may be possible to re-use some of the old brake lines, but if you are doing a full…
