Default Converter bolt issue.
I bought a Coan triple disk torque converter for my turbo Silverado build.

The flexplate has holes in it for #10 metric bolts but my converter Takes #8 metric bolts. Is the little wiggle room on the bolts going to be a issue for me?

I hope not I REALLY need to get this tranny in ASAP.

Would call the manufacturer on that one, but i would not be comfortable with that much wiggle room..

The M8's are the only ones that fit the pads of the converter. So thats what i used.

Converter to flexplate issues NO....I do know two of the pads on the converter do have heli-coils in them. I'm guessing the tap broke when they machined it and fixed it with the heli-coils. Maybe see if yours is that way too....

I had the same issue with my tci flexplate having larger bolt holes than my circle d converter. I ended up cutting some tube that was a close id and od just to take up some of the clearance so far so good but it would be nice if they were closer in size to begin with.
