ive got a 88 with a 5 speed. Am i crazy or is the fill plug some bastard size(question mark button missing). i swear thar it should fit a rachet, but it dosent.

 

I don't remember the size but there is a socket in your tollbox that will fit.

 

its a square hole. lol not a hex head.

 

use a bigger ratchet?

 

I found the same issue.... square, but too small to be 3/8 drive, too big too be a 1/4 drive.

I settled on grinding down a 3 inch 3/8 drive extension to fit.

Is there an actual tool that will fit this wierd hole?

 

Its a SST (special service tool) you can buy from the dealer or grind down a 3\8" extension with a dremmel which is what i did.

 

What I did as well. Thought maybe I was lookin at somthing besides the fill plug. Thanks for the reasurrance.

 

LOL long night.
