Rear legs are about 3 inches too long, the front legs are non MSA compliant & you need a good 10 - 15 hours of metal working / plate / box section making to get a good solid fit!
I'd plum for a safety devices cage hands down over OMP
P.S i have an OMP cage in my micra ( with alot of mod's to make it fit right) cost me more than the cage again to fit it!
