yep... bolt TC directly to flexplate ! if you have 1/8"-3/16" stab or clearance between the flexplate and the converter pushed all the way back to the trans . take a 1/8" drill bit and a 3/16" bit and see what you have . no less than 1/8" no more than 3/16" . from what you posted you have aprox .150" (without shim) that's almost in the middle of 1/8"-3/16", which is good . check out links . .

From TCI website :
What type of clearance should I have between the torque converter and flexplate before pulling the converter forward and bolting it to flexplate?
Answer: You should have 1/8" (.125") to 3/16" (.1875") between the torque converter and flexplate before pulling the converter forward and bolting it to flexplate.
