The frame bracket for the big V6 is about an inch or 1.5'' higher than an L6 [or V8] Generally those are flat on top of the frame, no arch at all. Never seen one like that.
As they are riveted to the top of the frame, no. not generally moveable, but, if you drilled out the rivets and shot new holes for grade 8 hardware, anything is possible. I think you need to acquire a non-V6 frame Z-Bar bracket.
I'll try to shoot a pic of one tomorrow. There's one still on my '67 K/10 Suburban, but it's been converted to automatic. Still need the bracket for a 292/SM465/T221 '72 K/5 project, so I am volunteering no hardware.

The conventional L6 pivot stud bracket is about 6.5'' wide. V8s' Z-Bars were shorter, had a pivot stud on a bracket almost flush with the wider V8 block, except on 4x4 [K-types] a stud screwed right into the block.

So you need to go on a junkyard hunt.
You need:
An L6 Upper Clutch Rod [good luck, they don't make 'em anymore, and the LMC repop is a joke -- might fit a Dodge, but not our trucks. My machinist fabbed one for me with heim joints in 2005. Now they retail them, but for big bucks]
An L6 pivot stud bracket. [as illustrated]
An L6 Z-Bar. [I''l have to pull the dimensions off my rigs tomorrow.]
A flat, Chevy-style [not GMC] Z-Bar Frame Bracket. [Not hard to find, but grinding one off a frame can be a b!tch... Possibly a copy could be milled out of some stout 1.5'' angle iron.]
A Lower Clutch Rod, [Easy enough]
A Fork ''nut'' [Looks more like a wedge]
There should be a lot of rustfree junkyards in your area, if it all hasn't been 'fished out' by high rollers from the rustbelt states.
Good Hunting.
