Off the top of my head, it's typical 1/4"X20. Probably about 1/2" in length will work fine.

1/4" x 20 bolts can be had anywhere. Home Depot, any hardware store, etc.

LMAO @ RamAir To OP Just type those numbers into your phone or write it down, I'm sure there will be enough dumbasses up at Home Depot to figure it out. Sometimes I think my mentally retarded uncle could be employee of the month at places like Home Depot and Lowes...

It's a 1/4-20 bolt, half an inch long. I believe the original has a 3/8 hex head, not a 7/16 head as a hardware bolt will. This larger head may make it's installation difficult.

If I had to do this, I'd try to get a Allen head bolt, it'll take a 3/16 hex drive and have a smaller diameter head. I know it's tight down there.

Seriously? Are the people of this generation so lazy they cannot look up information on their own?

Geezus...

You now going to ask how that was done?

i used a 7/16-14 bolt for the dipstick because I do not believe the stock bolt is strong enough. But I drilled too far into the block and now I had to fill my block all the way to the head studs to keep it from leaking. That dipstick tube ain't goin ******* nowhere... where you goin? nowhere...
