I would call Dave Stevenson at Stevenson chassis 712-371-9598 He is here in Iowa and builds frames I had a frame he build that was a non down tube chassis similar to that. What is the yr on the sticker on frame I used to race Knoxville as well Didn't think they started to inspect the frames tell 98 or 99
Ruled out gambler after talking to a couple guys that used to work for them. The sticker doesnt have a year just a number. Doug Clark and a few others have thought either Schnee or Wolfweld having a hard time finding pics of those.
Can you post a picture of the sticker I went & looked at a old J&J I had that I destroyed still sitting out side the # on it was 990284 that's was a 99 sticker the newer ones actually had the yr I thought all the Wolfweld & Schnee non downtube cars were built with the hoop behind the seat like a old Stanton the design of this cage
