I'm retired this year and now that I'm have some spare time I need to start working on my D port intakes. I have two options here,one is to use JB weld to build up the floor which will be anchored with a T-bolt system along with either aluminum mesh or fiber and I've used this in the past but my only concern would be near the short turn where anchoring isn't visible and lifting of the JB weld might be an issue. Second option using a flat plate of aluminum .125 that'll be anchored by three radius head bolts threaded from port to bottom of head and locked in place with green sleeve retainer. My question is what grade of aluminum should I use for the floor and can I use 5356 mig wire to seal the edges of the plate. Using a tig is out of the question there just no room and I can't use 4032 cuz my mig as no teflon liner, those birds nest can be a pain to unravel. Any input would be highly appreciated.
