Trying to identify A833 & shifter models

I'm finally back able to work on the '67 Barracuda. This was a slant-6/904 that's been swapped to a 360 Magnum and an A833 trans. I need to find the correct shift linkage for this configuration. It appears I have a Hurst shifter based on the patent numbers, but the model identification that should be stamped on the reverse lever isn't there. The transmission is a ball/detent style, and appears to be a pre-July 1, 1967 model as there's no machined area above the casting number. The crossmember looks to be pretty bastardized as well. Given the pictures, is anyone able to help figure out exactly what I've got, and perhaps which shift linkages I need? I think there's only one set for the A-body with a Hurst, but with this Frankenstein combination, I'm not sure if any will work out of the box.

The two numbers I can find stamped on the shifter are 6852R (picture #1, above lower right mounting hole), and 8327 that's on the plate that fits between the main U-shaped shifter body.

This is the linkage rod set that I'm hoping will work. Brewer's Performance - Mopar A833 4-Speed Transmission and Component Specialists
