?????

Hey all,
question, I got my 360 back from the machine shop, did a nice job. I had it internally balanced but they couldn't use my flex plate, said it was too far out so they balanced it with a B&M plate from Summit, which I wasn't offered even though it was balanced with that plate. could I just get a plate from Summit like they did? And what do I ask for when I order my converter, will this be a neutrally balanced converter? "WE NEED INFORMATION"

Also looking for a Dipstick for a 727, the one that came with the trans, the end was broken off?

THANKS ALL!!!!!!
