My chassis build

[HandyAndy]

the reaming should tke approx 10 mins per upright, just keep checking that you don,t go too far with the reaming.

as for steering extensions, are they the ones that are too long?
mine are from Rally Design & fit like a glove,
check the internal depth of the thread in the extension in relation to the length of thread thats on the actual steering rack, they may not be matching.

the mushroom is to sit fully into the upright with the offset hole towards the front of the car.

hope this helps.
