Need a Solid pinion spacer for diff build

[kevgentile]

Anyone have a source for a solid pinion spacer for the FRONT diff with the 4.88 29 spline upgrade?
The vendor I sourced all the parts from for the front and rear diff builds sent the wrong from solid spacer.
Now they think a solid front for the 29 spline doesn't exist.
It's possible that the 80 series will work, anyone?
I know they do exist and weren't one-off's.
I've reached out to a few other vendors with the dimensions of the existing crush, and pinion shaft.

I feel like if anyone would have it or know where to get it, it'd be Cruiser Outfitters.

Here's one that says it'll work—and the cross-reference is pretty large: Front Diff Solid Spacer Pinion And Shim Kit suitable for Toyota Landcruiser - HD Automotive - https://hdautomotive.com.au/product/front-diff-solid-spacer-suit-landcruiser/?srsltid=AfmBOop6jbN6x9nPp1kbB0MzK9Kxeq_hRXzLGonFYt6QOmc0FUwq77Q3. At least according to them, an 80/105 series 8" pinion spacer is the same as the HDJ100 and UZJ100.

What is the 29 spline upgrade? Either way a good workshop could just make one if you cant easily source.
