Not trying to reinvent the wheel. Just want to know what parts I need to make it work. '84 C10, short TH350.

Did the 99 LQ4 have the longer rear flange on the crank?

Is this the only way?

Why waste money buying something you don't need???

You need the stock flat flex plate that came on the LQ4. Then redrill it for the TH350 verter. Since your LQ4 is the longer crank you DON'T need the spacer for the flat flex plate. If you don't have the flat flex plate just get the later 6.0L flat unit. It will have the spacer on it simply remove the spacer from the flex plate. The bonus is you can use the that spacer to align the flexplate to the verter to help mark the holes for drilling other than that its not needed.

Praise white Jesus, now that is what the **** I needed to hear. I will see if I can grab one from the junkyard tomorrow. 5.3's have different flexplates correct?

Yup they are curved.

My pic is exactly what you need, 6 hole flat Flexplate.

Thanks Bo. Every junkyard here wants $50.
How do you engage the lockup converter on that th350, with the ls motor?

Bo185

Not a bad price. But I assume your motor didn't come with one?

The flaxplate is usually in stock at the dealer ship for around $70. the GM flat flexplate part # is 12621399. My wife gave me mine for Christmas. I ovaled the holes and it works awsome!!!!!

Correct, it was flexplate free, and now the local yard says they don't know what it looks like unless I bring one in to match up

'99 you don't know me very well, but you do know, like you I am doing a Ebay twin-turbo special; that being said, no way in hell am I paying $70 plus tax for that.
