Doing 4L80e upgrade on 99 firebird, I bought vigilate converter with 4l60 bolt pattern. I have tci auto flexplate. The bolts that came with converter are too short, the tci flexplate has extra material around bolt holes and I can only get two turns on the bolt before it seats down. thanks for looking

I think you have these M10 x 1.5x 16mm bolts

correct?

measure the depth of the threads of your converter mounting pads, and then get a bolt that will be 2-3mm shorter.. so you can leave a little for bolt stretch..
