One thing that always bothered me about the 25th Tele-vipers (aside from their hands :( ) were that they did not come w/ the cool back packs like the original '85 Tele-viper ( YOJOE.COM | Tele-Viper
So I got a hold of some original '85 Tele-viper backpacks and modified my 25th ones to accept the '85 backpack. The factory hold in the back of the 25th TV is too small and in the wrong position to accept the backpack, so you WILL have to modify your 25th TV to accept the pack. :(
Basically all I did was figure out about where I wanted the pack to sit, take a SMALL drill bit and re-drill a new hold in the new position. Once I had the small pilot hole, I then took to right size bit compared to the post on the pack (DON'T go TOO big!!), drilled out the hole w/ the bigger bit, and I was in business!
One thing though, do NOT go too far INTO the figure, b/c then you are going to have a TV w/ a chest wound also.
Anywho, here's the final product, along w/ the re-painted HK MP5 that came w/ the 25th Cobra Para-Viper came with. They were originally molded in dark blue and looked like hell, so I just painted them solid black.
Now my 25th TVs look almost as good as the original, I know they don't have the goofy gun and hose the original did, but I was never a big fan of that anyway.
