Hi. Just happened to stumble across your site and it looks to me that you might have, in your collection, a similar type of frame that I have. The particular frame that i'm looking at is the 84 Torker Pro. I have a chrome frame that I picked up in craigslist (for free might I add!) but it has a Haro sticker on it and i'm sure its not factory. I have a thread posted on www.vintagebmx.com about the subject --->
My serial is also on the dropout I remember.
But the bike is powder coated and build up and can't read the serial now.
But be sure it's a Torker.
There is no other frame that looks like the Pro-X!
The Pro-X is a high frame and that I've never seen in other brands! (long seattube)
