[T2] rebuilding a distributor

[Sami Dakhlia]

Hi,
The second project for my annual back-to-my-bus California trip is to
do something about the unsteady timing.

My take is that the distributor on the '75 bus will either need to be
replaced, or if at all possible, be rebuilt. I found new, so-called
SVDA dizzies online, but would rather keep the original dual-vacuum
advance distributor.

Am I correct to assume that unsteady timing is due to worn bushings?
If so, can those be replaced and can I do that myself without a press.
(I do have a hammer and a crowbar, though :)

TIA,
Sami
