‘81-‘87 4x4 Transmission tunnels

[Bob Q]

I noticed that our ‘84 K2500 with the factory SM465 has a one-piece solid transmission tunnel where as the ‘83 has the older style bolted/removable type tunnel (both are 4x4s with SM465s and high hump tunnels). Does anyone know if the transmission tunnels are the same shape between the bolted style and solid type? We were thinking of cutting out the tunnel on the ‘84 and fitting the older bolted style cover in its place. Anyone done this before?

Thanks.
