Fix the six pack Vipers?

[tunnelrat88]

The six pack, while a great idea on paper, was poorly constructed at least from the one that I bought. The heads do the normal viper lean forward and the legs have problems when you put them forward. Does anyone have a full proof method of fixing these problems?

Here try this out. I did it on a few of my Vipers. Works pretty good. I'm just to lazy to do the two sets I have. Thanks to Yorktown Joe for taking the time to write it up.
