Any A999 gurus out here? Input shaft and front pump support questions.

[RevboxRyan]

I have an 87 A999 that converter lockup came unglued and wrecked the input and some parts up front. Transmisson was freshly rebuilt before converter came unglued. Basically can I get a new front pump and stator support? What can I do to run a non lock up converter? Will a 904 input work with the other lock up parts?
