I find these threads very frustrating. A fellow asks a question and wants a "yes" or "no" answer and nobody, including me, can give that direct answer. However, a ton of information is given that would allow somebody to answer their own question. The fellow still keep asking for a "yes" or "no" answer and doesn't seem to be able to break the code and answer his own question.
I am tempted to make an observation about the breakdown of critical thinking skill is today's society and the desire of folks for simplistic answers without the need to think. But that is for another day.
Scott, you have all the information you need. Get out some tools and start taking measurements. If all else fails, buy a freaking 38 Special expanding die on Ebay, they are not rare and it will only cost a few bucks. It will either work or it won't, but to about a 99% certainly it will work with the proper size expanding plug. Take a chance and learn something on your own.
