I don't understand what problem an extender would present as long as the extender didn't hit the spare tire, put the bike rack too far behind your truck or cause the bike rack to wobble around too much. My bike rack didn't fit my first LS when I bought the bike rack back in 1990 but the hitch company where I bought the bike rack had no problem adding an extension to the rack so that it cleared the rear vertical plain of the rear bumper when it was plugged into the receiver. I've never had a problem with it ... I've used it five times in just the last two weeks and hundreds of times over 19 years.
Maybe it would be easier to have a hitch company supply a proper fitting extender or shorten an extender rather than modify your bike rack.
Maybe attaching your Thule bike rack to the extender with a bolt instead of a pin would make the whole assembly more rigid if that is the perceived problem.
Tire is in the way and you will need to cut any extension or the bike rack. As for extensions, it reduces tongue weight by half and bike will rattle.
I took a look at the rack and by cutting the rack, hole for the pin will be too close to the end of the rack. I fear it might not hold up in the long run. (less than ½ inch)
I have a high price carbon fiber bike I would not want to see her bouncing around on the rack with extension.
Why in the world would Lexus make such a hitch without proper adaptor?
