Outer Limits 4x4 Board

Blown my diff in my 04/89 ifs 4runner and am hoping to find out the diff ratios. Have been to that link in the bible and came up with 3.300 but am having no problems pushing 35s so not sure if its right.
Here are the numbers on the car
model. YN63RG-MDQ
frame no. JT711YN6309000402
engine. 4YC 2237cc
color. 147 HV11
trans/axle G52 G142
plant. A51 mar89

Thats all the numbers and I came up with 3.300 see what you come up with and let me know.
If anyone has done this before or has the same numbers and knows there diff ratios couyld they also let me know.

Cheers

G142 means you have 4.875 with a 2 pinnion centre.

G52 is the gearbox

Thanks bulldogboy I'd been told that dont know how you got it from that site though. I guess that will be an easy one to source

you have that on an 89 runner? gee, i just started looking at this on mine coz i'm looking at going 33's and mine has that same trans/axle code! what engine's in your's??
EDIT, don't worry re-read your post and saw the engine part of your plate on the firewall and saw the 4Y part.
