I can vouch for the guys at the parts yard.. Think of how many parts they go thru on a daily basis.
That and combine the fact that most of their workers are the type that probably wore helmets and ate their crayons growing up. Or did a bunch of meth and do that currently as a past time.
Just goin by from what I've seen local.

I had the lock up hooked up on my 700r4(which works the same as the th350c) with a toggle in the dash. I would just reach up and click it on when on the highway.

I have 2 5.3 flexplates I'm not going to use. I would be more than happy to elongate the holes for you and ship it to you for the price of the ride. Then you will have to get the adapter that goes between the convertor and the flexplate.
Or you can got to your local GM dealer and buy a new flat flexplate and spacer. They are cheap enough you don't need to use yard parts.
GM part# flexplate 12621399
Spacer 12563532
bolts 12563533 x6
This what I used on my 4.8L with the 700r4/TH350 and works perfect.

Thanks 99, unfortunately it's my understanding that I need an Lq4 specific flat flexplate, as the protrusion of the crank negates the need for a spacer. I have an extra 5.3 plate as well and its a no-go.
Did I already ask you how you are going to make our th350 downshift?

A TH350 will downshift manually w/o a throttle cable if you'd rather not run one. Using a cable will result in factory-like downshifts...

You're still gonna need the spacer for indexing the converter snout, without it the snout will be unsupported and will trash itself at startup.

99 lq4 has the longer crank. The convertor will reach without the spacer.

Just out of curiosity, would the 4l60e out of a '97 and older vehicle mount to the long crank LQ4? Guy got in over his head with the price of an actual ls swap (don't we all) and still wants to let the 5.3 and older 4l60e go for $400. I initially walked away from the deal because I wanted a newer 4l60e, but now...
Bo, Merv? Any input?
