Default LQ4 to TH350 Pics of problem included

Heres the low down, I have a th350 with a 4k stall I purchased used. I also purchased the gm spacer and bolts to go on my 6.0 flex plate, but the problem is the guy that I purchased the used th350 and stall from cut the outside bolts off the dual pattern stall converter!!!!! Now I messaged a few people on here and their response was to get a new stall which will NOT be happening!!

The question I have is : Can I use another STOCK form flexplate on my lq4 to allow me to bolt up a small bolt pattern torque converter.

Take the flex plate to amachine shop and have them drill it for the other pattern
Had to do it on a powerglide swap, that didn't have the correct bolt patern

I would get a new converter or atleast send that one back to the manufacturer to have the tabs replaced. I would be worried bout it be out of balance.

I have been looking at this thread. I am wondering if this means I can use the spacer I have + the bolts that I have and use a 4.8,5.3, or ls1 flexplate. It say's it will fit the small torque converter pattern, but not 100% sure.

The spacer makes the converter snout reach the end of the crank. It has nothing to do with your problem. Like was said above, have your flex plate re-drilled at a machine shop.

2. you do not need a special flexplate, the curved 4.8,5.3,LS1- just need the t/c bolt holes ovaled out a bit and the 5.3 flex plates have a set of holes that match the small gm t/c bolt pattern perfect

Copied that from the link previously... so your telling me a 4.8 5.3 or ls1 flexplate will NOT work with the small bolt pattern torque converter??? I am not having a machine shop drill holes in my 6.0 flexplate for 50-60$ when I can get a used 4.8 flexplate for 20$, just trying to see if it will even work.

Get a 5.3, 4.8 or 5.7 flex plate and the spacer from GM or Hughes and you will be able to use the small bolt pattern holes on the converter.
