Ditto on the great progress....
Those cab corners look really good compared to most...
Clean em out, vacuum, the hit them rust convertor spray paint...
Remember to keep at least one tank mount point clean of paint for good grounding...
Check those seat belt bolts and webs while you have access to them...
Re fuel hard lines...remember its your truck and we all make our recommendations...its not that we insist you have to do this or that..the filters should keep any crud out of the carb...if you start having clogged filters...well then you know the hard lines need changing...
Great progress...have fun...
