Foot-Pegs and Backpacks Question

I am looking at buying some Venom vs. Valor figs to fill my Terror Dome, but I was wondering. Are the foot-pegs from the old 80's the same as the VvsV pegs? How about backpacks too? Can my old Joe packs fit on the VvsV figs?

Also, how about the newer Real American Hero figs? Same questions.

As long as its not 25th.It should all work together.

Some will and some won't. Back pack pegs and stands weren't universal even during the old days.

Yeah for some reason Hasbro decided to change them for 25th instead of making them compatible with the 25 years of accessories out there.

The VvV should be the same, but the 25th line's footpegs & backpacks are smaller by almost half the diameter.

Cool. I wanted to pick up some fillers, but didn't want to fork out money for something I couldn't actually use.

Thanx!

Most of them will be OK but there are a few VvV figures that have really thin torsos and the BP sticks out a little bit.
