tilt shift indicator question

[ludwigmace]

I'd like to get a shift indicator back on my column and am having a rough time finding the parts I need. I've got a 1969 c10 with a TH350.

I'm missing the shift indicator pointer as well as the housing and PRN21 deal.

I've been searching the threads all morning but have had a hard time identifying exactly what kind of column I have as well as what parts I need to buy.

Per some of the other threads I've researched, I've checked out LMC but the model years and tilt/non-tilt designations don't add up. Maybe this column originally came from another vehicle? It also looks like there's a little socket in the column underneath where the indicator housing would go (second pic). PO thought this was factory tilt but I'm not so sure.

Thanks for any help!
