Anyone wheel Fourdyce?

Hello. I’ve got an 89 K5 blazer that I’m in the middle a decent transformation on. Going from leaf sprung GM 10 bolt on 38’s to a linked D60 on 42’s. I’m doing a wishbone style upper link with DOM bushings and Johnny joint for both rear link mounts and axle side mount on the passenger side with 2.5”X14” King coilovers.Tonight I cut and bent all the plate steel to box the frame in for the rear mounts. It’s coming along nicely and will be a totally different rig when it’s done

A work in progress. Front clip and engine are back on and in. Tailgate getting rebuilt now

We’re getting there on our 57” front spring swap. Although I need to get A different set of heavier duty springs ordered in extremely happy with how it is turning out. And getting the 91 front swap done at the same time.

What style detent cable seal would a 1976 th350 take? I can’t find anything on oreilys and I’m not sure if different years take different style seals.
