I need steering column help

[Phoax]

I didn't like my steering wheel position the day I bought my truck years ago, it's not tilt. I recently saw a craigslist ad for an early Chevy van tilt steering column and it said in the ad it would fit a 67-72 truck. I had heard of people using van tilt columns in the past so I bought it.

It didn't just plug in like I hoped it would.

I can't seem to figure out how to separate the intermediate shaft from the main column on my original column (blue)

How do I hook to black column up to the rag joint on the blue one?




Btw my truck is a 67' and it is converted to floor shift so none of the shifting bits are relevant, I just need to steer.

Thanks,
Matt
