I'm installing a Performabuilt level 3 4l60e and FTI 2800 stall torque converter and FTI says if my gap between flexplate and converter pads is more than .187 " I need to shim with .060" washers between the converter and flexplate. I've tried everything I can think of which mainly consists of using petroleum jelly on my finger to make the washer stick to it while I try to slide it behind the flexplate. I can't see even with an inspection mirror if the washer is in the right place and every time I think I have one or two and have bolts started, they fall out when I turn the flexplate to the next one. My gap is barely over the .187 , .20. If anyone has a cheat as far as installing the shime please let me know. It could be the TCI flexplate has a weird pad that's adding to the issue.
