Are there any one piece tracks will fit hobby boss's line of 7A1's? because i hate indy links all my 7A1's will go unbuilt because of these indy links.

I might be wrong. As far as I could recall, the only one piece track for AAVP-7A1 or LVTP-7 is from Tamiya (or Academy re-boxed from Tamiya). For the RAM/RS version, the track for Bradley kits (Tamiya or Academy) may do. Not easy to find them selling separately.

Academy did not license their knock offs of Tamiya molds, they just copied them, back in the bad old days. Indeed, the Academy LVTP7 kit was one of their first offerings that was not a straight copy--instead, they backdated Tamiya's LVTP7A1 to the original 1972 configuration. To their credit, in more recent years, Academy switched to designing original products.
That said, Rainbow Ten in Japan sells individual Tamiya sprues and, presumably, vinyl tracks, online.

I would GLADLY swap a set of rubber band tracks from a Tamyia kit for your seperate link set

I know its not what you asked for, but AFV Club makes a set of workable indy links, with seperate pads, just like the kit tracks, but FAR easier to work with and look outstanding!!! I built mine in about two hours TOTAL for both sides, and they look amazing.
Other than that, like it has been stated, try to get an old set of Tamiya or Academy one piece tracks.
Best regards,
