Torque converter to flex plate bolts
 

I am having a problem fitting new ARP bolts, Does it matter whether they go in from between flex plate and engine block with the nut on the transmission side or with the bolt head the transmission side and the nut between flex plate and engine block?

Naw, but there is forthought to put the nut on the softer-metal side, and the SHOULDERED bolt on the hard metal FLEXPLATE side.

Space the converter off the Front pump!, Grind the bolt length to ~ 2 threads after tightened.

Am I missing something? Shouldn't a Pontiac torque converter have welded-on spacers that are drilled and tapped? No nuts involved.

Must be after market hi-po converter?

Nuts and bolts is Surely not an original TH400 converter.

Or an original CHEVY converter, which doesn't clear the balance weight(s) on the flexplate.

Am I wrong? Chevys used nut-and-bolt fasteners, Pontiac, Olds, Buick, Cadillac used bolts into drilled-tapped standoffs welded to the converter.

Thanks once again for the replys. Its a TCI Saturday night special. Never had any issues and have been using it for many many years. I don't recall ever having a converter with captive nuts or welded on threads.

All GM stock muscle 12" & 13" seemed to have welded nuts. 3 or 6.

The tiny 9", 10", GMs may have used loose nut& bolt.

11" cores?

My after market 9" converter has welded on nut. Went to put in original bolts and found converter was metric.

Most all of mine use nuts and bolts. Grade 8s.

I have a GM converter that has 6-welded on lugs with standard threads. Has GM part number 8625982 stenciled on it. It’s often referred to as the Chevy “L88” converter. Never saw a factory installed 6-lug converter in a Pontiac.
