I am fitting the RD front and rear floor pan pieces for replacement.
The front and rear overlap. I am assuming I should fit and trim and then butt weld them together. Would there be any reason to overlap and lap weld them? Thanks -Andrew |

Butt weld. It's worth the effort.

If there is no significant strength benefit to the lap I would prefer the stock look
Thank you -Andrew |
