Is this type of bumper legal, specifically the part where there is an l-bracket sticking up from the bumper, the top the l-bracket is at exactly 7.5in off the ground when on the bot.
That should be legal. That said if you are using a center drop drive one end might end up higher than 7.5 in.
Also keep in mind the weight limit on bumpers. We used angle aluminum like that last year and we were very close to the limit.
