Hi mine is the glass tek cause they have the reverse lip on the inside so you can mount it like the factory did with the clip nuts and the bolts from the underside. Russ
Got this steel scoop from Harms some time back. It was around 650, so it wasn't cheap, but was a very high quality pc. I believe he was having someone in South America making these when he was affiliated with the guy down there. Not sure if you can get one at this point...
I just got the VFN scoop, least expensive one out there but you get what you pay for. It'll work for my kids first drag car but I wouldnt use it on a "nice" car.
I asked this years ago when I was purchasing one. I followed everyones advice and went with Kramer. Not cheap, but when ever the RO23 scoop gets asked about, it's usually #1 for quality. Cheers!
