FairladyGTR Posted January 29, 2020 Share Posted January 29, 2020 Hey guys, im fixing to start welding my floors and the bad dog rails.... should i just stitch weld them or plug weld situation....? Quote Link to comment Share on other sites More sharing options...
rturbo 930 Posted January 29, 2020 Share Posted January 29, 2020 240 or 280? If it's a 240, I'd put em in like factory with spot welds since they have a flange on them. The 280 rails he sells I don't believe have a flange, and I wouldn't want to weld them directly to the floor pan due to the lack of surface area the rail contacts the floor with.

rturbo 930 Posted January 29, 2020 Share Posted January 29, 2020 Early or late? Early ones will have 240 style rails. Quote Link to comment Share on other sites More sharing options...

Ironhead Posted January 30, 2020 Share Posted January 30, 2020 I installed them on my early '74 260z. In my case, I plug welded them. Most of these cars have bowed /damaged floorpans. I found that by drilling holes through the floor/stock rails/Bad Dog rails, I could use M5 bolts to draw it all tightly together. This pretty much straightened out my floor pans and the stock rails. IIRC correctly, I made plug welds every inch. Quote Link to comment Share on other sites More sharing options...
