GOOD DAY , "OVERDRIVE" .
Your tow ball "extension" is not an extension , you have only the removable part of a two piece tow bracket . The rest of the tow bracket remains on the vehicle . Many tow bar manufacturers make one bracket to suit many models , but supply an interchangeable bolt on section to suit various bumper heights or styles .
I hope this has helped you in some way . You could adapt it for a front tow hitch , or adapt it to use as an extra spare wheel bracket .
Cheers for now . Now go four wheeling for the enjoyment of it !
Can we get rid of STUPID DRIVERS before they kill us ?
