Another Mod to roof rail

I was asked about the cross bar I set up. I think it's better to have a write-up to explain and this may helpful to someone else.

I used to have a long cargo box(over 92" long). The position of the normal cross bar on 4Runner's roof rail is very awkward. I can't put the cargo box on without interfering the opening of tail gate. I can't move the cargo box further front either because the front cross bar can't be moved further front any more.

I didn't want to go with a full length rack like GOBI's, so I made a "roof rail extension bar" like this:

I drilled a hole in the front end, so I can fasten my home made cross bar later.

The is how the "extension bar" was fastened on factory roof rail. The front:

The rear:

Took off the "extension bar"

The bolt was inserted into the roof rail. The giant nut here was not for fastening, it's used as a spacer.

This is the tricky part. You have to use a bolt with a square end and a correct diameter. So when you fasten the nut, the bolt won't rotate. This kind of bolt is used on wood post, and can be found in HomeDepot.

And the giant spacer nut:

This spacer nut was used to make a clearance for the roof rail cap:

My original plan was to make an "extension bar", it turned out to be a "platform" that you can secure anything, like cross bar, light bar, onto it, just use your imagination.
