Help! torque converter

[Jackie Mac]

I have read and studied everything in this forum and elsewhere on how to properly install a torque converter. I just had my TH350-c (Lockup) trans rebuilt. I ordered a new conv. and went to install the trans. and there is no gap between the Flex plate and the conv. I literally spent 30 minutes taking the converter on and off, spinning it back and forth and every thing else and I am as positive as I can be that the Conv. is seated properly. I replaced the rear engine seal while I had the trans dropped and the flex plate is on correctly. I even put the old torque converter back on to check the gap and it also has no gap. I understand that there is supposed to be 1/16 to 1/8 gap and the converter should turn freely. The man that rebuilt my trans. is supposed to be very experienced but I am wondering If the correct pump was used in the rebuild? Any suggestions or ideas? Does the lock up trans also have to have the same 1/16 to 1/8 gap? Thanks much for any help
