A lock up converter will NEVER have a drain plug in between the converter bolt pads,so if they both have drain plugs they will work. Also ,a lock up will have 23 splines for the input and a Non lock up will be 24. (hard to count inside the converter though) .
As I've said before, Terry you are a legend.
Anyway, it looks like Bart has a converter more local than mine.
While we are on the subject Terry, can you confirm if I'm right about a smaller converter on a larger engine will generally = more stall ?
I plan to use my 10 and a bit inch one behind my Magnum 360 (I know it needs to be weighted, I have got the right weight to add for the Magnum).
