Your best bet is to buy a new/refurbished from parts geek, $229 then adapt the locking brkt off your 2.6 if that’s what you got, the 2.3 brkt is a little longer than the 2.3.
I have a 2.3 used dizzy that I got off a guy here, but the vacuum advance was stuck, soaked it in pbblaster, it moves now but think diaphragm leaks when you suck on the hose.
If you want the used dizzy I’ll sell it to ya cheap, and I can custom the lock down bracket too if you need help. The lock down brkt is the hard to find piece for the 2.3…
Any other questions hit me up, I just did the carb swap on my 2.6 90 model trooper.
