I know a lot of people will say to just search this and believe me I have been.

I was talking with Chris at Circle D who recommended me a converter for my 04 2500hd 6.0, 4l80e with a BTR stage 3 cam. But I was told I need to change flex plates to a dished style out of a 4160e. Can someone tell me if any of the attached flex plates will work, or point me in the direction of the OEM part # or something that will work. Chris gave me some part numbers for a TCI one and their billet flex plate but I really don't feel like spending $500 on a flex plate.

I understand all of those are very cheap, I'm not looking to cheap out on an essential part those are just the parts I was able to come up with.

Any help is appreciated, thank you.

I'd assume you currently have a 60e and are upgrading to a 80e. If so, just have him build a converter to bolt up to a stock 3 bolt dished flexplate. I have one and fitment is perfect. Just had to use small spacer between flexplate and converter pads for recommended 1/8 inch gap +/- .050. They build great converters. Packaged great and some sweet swag. Even a nice letter in an evelope to make you feel special.

Forgot to add. Chris will build you a converter with any front cover you need to match your current flexplate. Shouldn't need an aftermarket one.

Yep - had Chris do this for me when I did my 80e swap. But, if you're planning on adding power you're best to upgrade the flexplate while you're at it - the stock 60e plates have a tendency to crack under more than stock #s. A pound of prevention, as the saying goes...
