Harrier,

The head flip is not too dificult too handle. There is a whole post on RR for you to read on. It is Cal 30 no more wobbles There are pictures and if you have any quistions we will help you out along the way. As for the reason it was done! It is supposed to take out the wobbles that everybody has been experiencing. CK from West Palm Beach did the make over. Now you will have to change some things in your radio to make it work because you are flipping the head. To answer your question on needing to purchase new parts NO. You will need a little drill bit for the block, but other than that you will work with what you have, and it will work just fine. I don't need to go in details because on RR there are instructions. Well I hope this helps.
