One of the biggest T-800 wobbles fixed!
 
Have you noticed how bad the pelvis to knee tendon wobble is with the supplied 'floppy' parts. I can see that they could be useful to give a sitting possition, although I doubt that's what anyone will do with their T-800. Having explored this, I cannot see a good reason as to why we have another wobble on the T-800. With these new parts, leg articulation is just as good.
 
What you have is a set of 4 replacements. Quality part replacements, which are rigid and remove the majority of wobble.
 
Supplied ready for primer\paint.
 
Do not force the new piece into the existing area... it should be a snug fix and to achieve this, you may need to lightly sand the new part.
