I was going to say eBay as well and I’m digging your truck can’t wait till you get it finished and on the engine replace all the water hoses yes every one.
When we took off my Diff to install a Posi Lock some teeth were messed up so I put on some 3.73 gears on it along with the Auburn Posi unit I found on eBay.
Now on rainy days it’s a lot of fun slipping all over the place
On my 1993 I had the 4L60e rebuilt several times till I bought a rebuilt one from O’Reilly’s Auto Parts and now it’s trouble free well worth the extra money.
I had a nice truck like yours I put Craigers rims she looked sweet in fact when I went to look for another new truck someone wanted to buy my truck I traded it in and it sold that day.
Let me add this my dad had a 1976 Scout well sneaky me said let me go into a muddy road no cop can come in...
To me the best thing I did was remove my EQ and installed a Alpine stereo cd player with hook up for my iPods so that’s all I hear now is my iPods just one has over 15k songs so I love it.
