Well, it looks like I won't be ordering the RAM AIR box. The original radiator support does have an opening the driver side to hook up a dual snorkel system. My new '89 - '91 radiator support does not have any opening for a dual snorkel hookup. I guess the '89 - '91 burbs, jimmy's and blazers have the air inlet located on the passenger side fender. Guess I'll just have to go with a crowl hood. Hard part is find a metal one to fit my truck.
