Changes to provisional patent drawings

Changes to provisional patent drawings
« on: July 12, 2017, 12:34:42 PM »
In the time since I wrote my Provisional Patent, I have discovered a slightly different way to execute one of the features. My description is fine, and fortunately covers me regardless. However, my drawing would be slightly different if I were just submitting the provisional today.  Can the final execution of my product look slightly different from my original rendering, and still maintain the original provisional filing date?  Or should I spend the money and re-apply for a provisional, with the updated drawing?  I don't want to wait until I do a non-provisional, because I don't know if or when I will be doing that; I'm afraid someone will start producing my idea before I can get to it.
   Thanks in advance.

In my opinion its worth the extra $65 to file an updated provisional with the updated drawings.
