RV8 Hotwire Plenum

[need4speed]

Before finally fitting the plenum onto my V8 id like to know if theres anything on it that should be rebuilt or checked for wear? Especially on the throttle linkage side. Ive noticed that on the throttle spindle there are some bushes. Are these prone to wear?

Id just like to pre-empt any potential problem areas on the plenum before i attempt to run the engine up.

Thanks
Phil
