im going to be installing a v6 third (and doing a disc swap with chromo axles!) into my 86 xtra cab in about 2 hours and need to grab a freeze plug to plug the abs sensor on the third. im 90% sure i need a 3/4" plug, but just want to make sure. thanks

 

here is a thread on that..........http://www.pirate4x4.com/forum/showthread.php?t=587522

thought I would add a pic and info where to buy them Napa stocks them, part number 219-3038. Cheap and easy to get. Easy to install: just slide a socket into the cap and tap a few times with a hammer...
