converter spacing issues
you need to "shim" the extra space...
you need a "pull out" distance of 1/8 to 3/16
seat the converter fully in the transmission, pull it back out 1/8 of an inch, shim the remaining distance...
easy way to figure out your shim is to seat the converter fully, then grab a 1/8" drill bit, hold it up against one of the converter pads... measure the remaining distance to the flexplate mounting points...
do the same with a 3/16 drill bit...
any shim that falls inbetween the 2 sizes is fine to use.
since you know your distance is 5/16... you need to find a shim that is 3/16 (0.1875) maximum, or 1/8 (0.125)minimum
there are a lot of premade shims that are 1/8" (0.125)
make sure the pilot goes into the flexplate/pilot hole at least 1/8 of an inch... if it doesnt, you also need a pilot spacer/adapter

but you could always try a pilot spacer from the 4l80 trucks with the flat flexplate
also...as long as you have an 1/8 of an inch in the pilot, you will be fine...which means you can just do the .125 shim.... 3/16 pullout is fine on a 4 speed transmission.
