I like the roof rack and would also like to know who made it. But as for the bumper, this was a little down the page: "... I made custom bumpers front and rear and put some lights on the front bumper."
Thats the safari roof rack, very hard top find now, even harder to find one in good condition, Best bet is ebay I found two on there over the last couple of years. One had too much rust to use, the other which i currently use was perfect and only cost me £50
I have the calmini one, it just doesn't look as nice as the one in the linked picture, and the side rails on the front allow you to put more stuff farther forward on the roof without preventing removal of the soft top.
