Hi.... I'm having a bit of the same problem. I've got a frame with similar serial numbers. Previous owner says it was ( to his believe!) an Avalanche but not sure on the year... the serial is similar but it has several other numbers on it. So I'm confused about model and year... here's a photo. Thanks in advance for any help on this.Well that is exactly the same as my aggressor, the dropouts are exactly the same, 7005, same GT badge and same brace.
My frame number is RZ0802707
