gerktj Posted November 1, 2013 Share Posted November 1, 2013 what size are the bolts that hold the transmission to the motor on a 88 4.0? Link to comment Share on other sites More sharing options...
onlyinajeep726 Posted November 2, 2013 Share Posted November 2, 2013 7/16"-14 for the bottom ones and 3/8"-16 for the top ones (get hex heads to replace the E12 inverted torx). Length of the bottom ones are not an issue as it can't bottom out in the block, but the top ones can bottom out so make sure to measure the old ones. I know my hardware store didn't have the exact length, so I bought longer ones and ground off the end until I had the right length for each. Also, word to the wise... Get SAE8 bolts and make sure they are not Made in China... Taiwan and the good ol' US of A is acceptable. :USAflag: Link to comment Share on other sites More sharing options...
cruiser54 Posted November 2, 2013 Share Posted November 2, 2013 Top ones are 1.75" Link to comment Share on other sites More sharing options...
onlyinajeep726 Posted November 2, 2013 Share Posted November 2, 2013 Thanks Cruiser... I was thinking that but didn't want to say for sure and give the wrong length. Lowes Home Improvement only goes in half sizes (at least mine does). I remember now I bought the 2" ones and ground off a quarter inch. Link to comment Share on other sites More sharing options...
