frame drain holes

hello everyone,ive been fighting a rusty frame for a while now and ive read more post about it than you can shake a stick at,my fix for this is a little bit different,i live in Michigan and rust is a huge problem here,the whole inside of my frame was full of crap,the rusty pieces were way to big to fit through even a 1" hole so what i did was cut slots in all 4 corners just inside of the lower control arm brackets.the slots are 3 1/2 long and 1 1/4 wide,i used a 1 1/4 hole saw at each end of the slot and used a cutoff wheel between each hole to cut out the centers,then i welded 1/4'' plates with a little bigger slot cut in them over the slots in the frame,the reason the plate holes are bigger than the frame holes are you can weld around the inside of the slot to,my frame has no rot but was full of rusty flakes and dirt,if yours is like that to small holes wont let the bigger pieces out.......then i moved on to the trans skid plate area.i got all but 1 of the bolts out and had to cut off the last 1 with a sawzall.i could have just welded the nutsert back in but thats not me.so i cut a 1'' slot from about 1'' outside of the front and rear nutserts that cuts all 3 nutserts out(you wont believe how much rust is inside your frame after you cut out that piece)i then made a 3 1/6 thick piece with 5/8 nuts welded on the inside for the skidplate bolts,place the new piece over the slot you cut in the frame and full weld it on,i drilled holes next to each skid plate nut for drainage,what you end up with is a way stronger way to attach your skidplate and slots big enough for everything to come out,i also put in 3/4 spacers between the frame and skidplate.i hope i explained everything well enough. ill try to post pics but cant get my camera to link to computer...

The Eastwood frame coating is good stuff. Be sure to tape all the holes in the frame to keep it inside. I used 5 cans. If you have a lot of rust/mud piled up inside, attach a 2' section of silicone tube to your shop vac. Use a coathanger to knock stuff loose.

after i had the slots cut in my frame and the plates welded on them i cut the long slots for the skidplate bolts i beat the crap out of it with a hammer to knock all the rust out of the frame.you would not believe the amount of rust and dirt came out.it would have never came out through small holes, if you still have the stock nutserts for your skidplate i highly recommend cutting the old ones out, with the long slot cut in the bottom of the frame its nice to be able to clean out the inside of the frame plus the whole frame from rear lower control arm mounts to front lower control arm mounts is twice as thick as the stock frame,the nuts for the skidplate are full welded to the new plate so theres no way their going spin now.i wish i would have taken pics as i was going.its not hard at all to do,theres nothing to bend or cut off,just cut out pieces from the bottom of your frame its 2 1/2'' wide and flat
