Sorry beetlebz, been busy helping wife open her new biz.
Bud is absolutely correct, almost all of the suspension parts on the GT fit the original 10T. I also have two of them - been through T2, T3's and sold them all, kept the originals because I like their handling BETTER - but the single thing you can do to improve the 10T and keep it competitive is add a chassis stiffener. I used two graphite strips that go from the shock tower to the two tube brace stiffeners.
This eliminates the axial (twist) and longtitudinal flex and it drives like a completely different animal, check it out.
As for servo mounts - they ordinarily mount flat on their side and sideways, but this pitches the servo linkage at an angle to the steering bellcranks, giving you more steering to one side than the other. I hate that!
So I mount my servo on top of two RPM servo mount blocks with the servo horn facing down,
and drill a small hole in the chassis to access the servo horn screw.
The same old pics I''ve always had show both the braces and servo mounting and can be found here.
