never seen that one...
Okay, here's a pic of my hardtail savage:

It's undegone some more change since then. I made the struts out of 1" rebar, 10.25" long, center to center, ~14mm (0.552" or so) holes, no rubber gromets. Welded and heat treated the bushing on there with a TIG (bob at the machine shop did that for me). I chose the length b/c that was how the stock shocks were when I sat on it and I did not want to change the steering geometry. In retrospect, I may have gone to maybe 9.5". The bushing are made from 1" OD cold rolled steel. I THINK they are 18mm or so wide.

Advantages: more power to the ground. Looks cool, is cool. Puts hair on your chest. Very fun to ride. It is NOT the same bike at all anymore.
Disadvantages with STRUTS: no two up, can bend frame. can bend frame anyway. money leaves your pocket and goes into your chiropractor's (actually, not too bad yet). Very hard on this cheap bike.
Now, there's the proper way to hard tail a savage:

with a different fender, it would be possible to take a pass.
