Happy Saturday morning everyone. I have just bolted my 2004r to my 455 and have a question regarding the air gap between the converter and the Flexplate. Most manufactures say to have a minimum gap of 1/4” but wanted to first check to see if I should be pushing the converter all the way forward before bolting. The converter is fully seated yet I can move it front to back so my question is, should I move it forward towards the flex plate and then bolt it or should I push and seat it fully back then bolt and shim with washers to insure proper gap? This is a art carr converter and transmission in case it matters. I attached two photos, one pushed forwad into the flex plate and the second pushed back into the transmission. Thanks in advance for your feedback everyone.
