'66 IDIDIT install without cutting stock column?

Good afternoon!
I purchased a floor shift column, IDT-1120610051, after a few phone calls to IDIDIT I thought this was a simple un bolt, remove, replace. I now understand I would need to cut the stock steering column. While it's banged up, i don't want to completely destroy it, and was wondering if anyone had found a different approach? My preference would be a rod that looks stock that I could purchase and cut to length, but really up for any suggestions.

I've already purchased a rag joint with the Lee steering box, so somewhat loath to throw that away with a new rag joint. Car hasn't moved an inch yet with that joint...

Thanks!
Greg

Re: '66 IDIDIT install without cutting stock column?

This has turned into more of a major project than I ever would have thought. Is there any reliable source for rebuilt stock '66 columns? The Ididit probably isn't that difficult, but they recommended a coupler for installation that takes a 3/4" DD shaft, and I would prefer to keep a round shaft like the stock column.

I can't even find a shaft with a flat spot on the spline area, like my stock shaft has. I could cut a round spline in theory, however it is a tapered cut, with the end designed to catch the bolt on the rag joint to prevent it from coming apart, and I'm not sure how to find a machinist that could do that.

What parts do you need to make your column acceptable to you? I may have most of those you need. BTW, they are fairly easy to reassemble.

Re: '66 IDIDIT install without cutting stock column?

On my 64 El Camino (long one piece steering shaft from wheel to box), I trashed all the stock stuff and started over. Parts used:

- Jeep box (have one in my 71 and love it)
- New rag joint
- Rag joint end from a junk yard column (needed one that I could cut off near the joint and slide the round shaft into)
- 36 spline round shaft (36" long from Summit, have enough left to do my 64 Malibu)
- 1" double D to 36 spline u-joint coupler
- Aftermarket column with 1" double D end

The fit of the round shaft into the junk yard column end is pretty good, cleaned it well and and did a nice weld after marking in for position in a mock assemble. Some will say to never weld steering components but the factory did in the same area with thinner steel and crappy welds.

Could have used the later collapsible factory shaft but it was bigger and I really didn't have enough of the slip fit area engagement to be comfortable as it really needed to be ~2" linger (it was also bigger around and I worried about header clearance).

Anyway, one way to solve it if originality is not at the top of your priority list. It looks very good but, fits the street machine vibe but not stock in appearance due to the stainless U-joint coupler (maybe some flat black paint would hide it)

Re: '66 IDIDIT install without cutting stock column?

This is the perfect opportunity to install a two piece (collapsible) steering shaft that became standard on all 67 and up Chevelles.

In a front end collision without a collapsible steering shaft, the first thing to collapse could be your chest. YMMV.

I was told on this site that the 67 collapsible column does not easily fit into a '66.

I used an aftermarket unit from Borgeson. You can get them at summit.

Thanks Senna, and good point. I don't disagree, but not sure where to start. I'm assuming I would need a rag joint and shaft, hoping the upper coupler from Ididit would work, its a 3/4" dd.

Thanks! The part is the last part in the column. The original owner crushed it to install a steering wheel he purchased, and I haven't been able to find this separately, and not sure how to replace it. Really would be awesome if you have one. The car isn't original at this point, but trying to limit taking that too much further.

Re: '66 IDIDIT install without cutting stock column?

I installed the collapsible column on my 1965 when I did the Ididit column. We welded a connector to adapt to the collapsible column part. I think it was a bolt on part but we tach weld it to make sure it did not come off.

It would seem like it's the same as using a straight DD bar, just need the rag joint in the bottom, cut to length, and coupler at top?

I believe this is the telescoping shaft I used.

I can't find the part number for the rag joint I used. You would be wise to call Borgeson and talk to them.

There were 2 styles of that part in 66 due to 2 different manufacturers of the turn signal switch mechanisms. I need to know which turn signal mechanism you have. One style is all plastic stamped "GUIDE" and the other has a metal base and stamped "BPC".


First pic is "GUIDE"







Second pic is "BPC"

I think from what I can see it is the metal style? If that isn't it under the turn signal, I'll have to find out how to disassemble more of it tonight.
Really appreciate the help,
Greg

Re: '66 IDIDIT install without cutting stock column?

I have that column cup. It's a BPC style.

A little bit of corrosion on the inside but pristine outside. Primed and ready to top coat.


PM me for pricing if interested
