just to add this to this thread so when someone searches it helps them..
is there a list somewhere..
try'n to get the oem patterns for
th350 [COLOR=red]- 10.75[/COLOR]
th400 [COLOR=red]- 11.5[/COLOR]
2004r [COLOR=red]- 10.75[/COLOR]
7004r [COLOR=red]- 10.75[/COLOR]
I bought mine and measured the bolt pattern from hole center to hole center and it was 11" and lines up with my extra th350 I have that I forgot I had ..OOPS
so I'm thinking the 10.75" is from inner edge of hole to inner edge of hole..
anyways.. hope this helps others..
FYI these pattern # are factory...
aftermarket converters don't always follow these ..
