tighening up the gaps

IT IS POSABLE I have done it, it is a pain in the you know what & it takes a lot of time. I set my gaps at 1/4 inch. It is well worth the time. I haven't used a welder but some times I have used duraglass to help out in certain areas. The only areas I have problems with are where the fender meets the cowl & where the fender meets the rocker. Good luck
