Just get and install the 5v GP's and forget about programing changes.
Many have done this and so far no one has reported any problems in doing so.
What they have reported is much better cold weather starting ability with the 5v versus the 7v GP's.
Some have had their 5v GP's operating on the 7v programing going on two years or better now.
If you do a search on LOST, there is lots of reading concerning installing the 5v GP's on the 7v system.
But please do get those ceramics out of there, if one of them breaks off, it could get real ugly and very expensive!
