4.30's were avail in certain:
4 cyl tacomas
3rd gen 4 runners
2000 V6 4wd 5spd Tundras
T100's

The Front diffs from the Tacoma, 4runner & Tundra will fit the Tacoma

In the rear (non-TRD) - The T100, Tundra, Taco will fit
If you have a TRD-/E-locked rear- the 4Runner rear will fit (as well as 4.30's from older gen 8")

What I don't understand is why toyota gave these 4cyl manuals such low gearing compared to the relatively higher gears found in the other 4cyl manuals. Was this part of a towing package or something?

In some cases- it followed the tire sizing-
If a vehicle were ordered from the factory with a tire upgrade- say from 225 to 265- it received lower gearing-
Also, certain 4cyl Tacomas actually had lower geared 4.56 from the factory- probably 4cyl w/ auto tranny
The fact is Prerunner/4wd Tacomas came with anything from 3.58, 3.91, 4.10, 4.30 & 4.56....
I don't know the magic combination......

Good luck with the search-

I have a spare 4.30 rear diff but its not for sale unless the price is right-
Its a back up diff since I have 4.30's w/ front & rear ARB lcokers in my V6 5 spd XtraCab-

If you have the $$$/and or patience, you can find them-
I think I have managed to score 3 sets of front & rear 4.30's in the past 3 years.

I would offer this suggestion-
Post in the wanted section or possibly offer to "buy" lower gears for someone that has 4.30's
There will be guys with 4.30's that want to regear to 4.56, 4.88 or 5.29.
The problem is when the cost begins to equal or exceed the price of new 4.56's.
Price out what it will cost you in parts & labor for new 4.56's - use that as the ceiling for sourcing 4.30's
