torque converter to flex plate hardware

[Zancat]

Bolts look like they should be 5/16-24 X 3/8. Correct?

Specs? Grade 8, flanged?

This little stuff is starting to kill me! LOL

Zancat, if you gauged it for your application you're probably correct however; you may want to use flex plate/ converter bolts instead of off the shelf hardware store bolts for this application. If the car is pretty much stock you'll likely be ok but this is a pretty important link in your driveline. might want to use an automotive fastener for this one. I would take the time to find the spec'ed bolt. good luck.

Spring for converter bolts from a place like Summit.... Mine have a lower profile head, so it clears the block when it spins...

First link is the size you described:

Second link are larger 7/16th size:

Uh-oh, I might have a mismatch. Hole in flex plate look like 7/16 size would be right, but TC is 5/16. The hole to bolt clearance should be close, right?

Yes,,, they should be the correct hole / bolt size on the flex plate...
Mopar Performance brand has the 5/16 bolt size flex plates.... Not sure on other brands....

Arp has these bolts as well

Ordered the Mopar Performance flex plate and hardware early this morning. I'll confirm it works / fits after I try it.

Rather than fart around looking for different bolts, I ended up getting OEM ones from Rick Ehrenberg.

Just a tip, the flexplate and torque converter bolts aren't equally spaced, one is a lil off center. So before you install everything, be sure to line up the flexplate on the torque converter and match the holes up, then mark that set of holes with white paint so you can line them up once the engine/tranny is in the car. PIA trying to spin the flexplate not knowing what holes line up.

Thanks, I noticed that. I used a silver sharpie.
