I have a 90 Jimmy with RWAL. Does anybody know if it is legal to remove it and just plumb it normally (like a pre 90)? I'm thinking about changing to rear discs and don't want any/deal with any ABS problems. I've seen tons of laws on emissions and air bags but nothing on ABS. For that matter, can you remove 4WAL on newer Chevy's and still be legal? Is it really an inspection issue in any state? In my state (Texas), all they seem to check is if the brakes stop properly, but not how they stop (locked up, didn't lock up, etc).
