67 PS and shaft into a 66.

[vince1]

About a year and a half ago I found a 67 in the auto wrecker with power steering and a collapsible steering shaft. I bought the plates to mount the box onto my 66 frame and changed out the old single spear shaft to the collapsible D shaft. The truck still has the 66 column and everything seemed to fit into it quite well. I seem to recall something about a 67 shaft could fit into a 66 column but nothing newer, yes or no for the benefit of others? The pump bracket I modified IIRC from an 85 Buick to fit the 230/250.

From searching old threads on PS upgrades there was mention of but no answer as to why the idler arm should be changed. I never did that so am wondering what the reason for that is. Everything works great as it is. If someone could help me with that, many thanks.

I think it's the Pitman arm that needs to be changed, not the idler arm. Basically, if you get a slavage yard PS gear box make sure you get the Pitman arm along with it, and the hoses too.

I have not done it, but that's what I remember.

The idler arm does not need to be changed. However I always recommend changing the entire original steering linkage for the newer linkage from the donor truck. This eliminates the need for those aluminum tierod adapter sleeves, plus it eliminates confusion of what year/application parts to get when the need for replacement parts arises.
