Replacement Torque Converter Bolts

When I pulled my transmission out last week, 5 out of the 6 torque converter bolts were the normal 5/8 head, and 1 was a 9/16 head, but the correct thread size. Has anyone else ever run across this? My guess is whoever had it apart before lost a bolt and Mickey-Moused it with another that fit. Can I just go buy some grade 8 bolts the right size and put them in, or is there something special about these?

There must be something different about them. I see some "kits" out there being sold. I can't imagine what they would do differently from a standard bolt.

You got a point I just changed my tranny and the shop gave me some different bolts they told me they were stronger, they were the same size as stock but looked different it had a design on the head, I can find out tomorrow if u still need the info by then.

Sure that'd be great. I'm living and working in the middle of nowhere, so if I can use some G8 bolts then sweet. If not I'll have to wait for a trip to town.

Well Revmax said that if I could find G8 bolts the correct size that they would work just fine. The problem is, I can't. I can get stock ones from Dodge for the utterly ridiculous price of $9 per bolt. Does anyone have a better source?

the 9/16 head are from a gas motor. at least that's what they use I work in a tranny shop

Do yourself a favor and get non-dodge bolts. They have a shallow head and are easy to strip. Fastenal can get whatever you need.

That's good to know. Thanks guys. Unfortunately I'm up in Northern BC right now, so we don't have those suppliers. I might be able to get a friend from state side to send me some if I get the specs exactly correct.

I might just have to swallow the stupid stealership price tag so I can get this puppy buttoned up...
