Here is the modifications I did to my k frame and lower control arms. The K frame reinforcements are circled in yellow and I started with cardboard templates for all of them....don't laugh at my welds....I'm an amature. The K frame has been seam welded all the way around...everywhere I saw two pieces of metal meeting together without a factory weld...got welded...and I mean everywhere.
This picture is an overall of the K-frame in process of recieving disc brakes and a PST polyurethane suspension kit. The recieving car is in the background and under the car is a dana 60 3:54 differential. The car is getting a 512 stroker (nearly complete) and 4 speed (complete). I also have to tie the frames and install torque boxes (have parts....need time).
This is a poor picture of the back side of the steering box plate on the k-frame. I see a previous post showed a crecent shape piece of steel to fit in here. I chose to just weld it solid without a plate. It really didn't take very long to do.
This is the other side of the steering box. a relatively simple triangle plate with no bends.
This is a plate under the drivers side motor mount on the back side (towards rear of car). It did require a bend to match the contour of the factory plates
This is a plate under the passengers side motor mount on the back side of the k frame. Odd shape and required a bend.
These are two plates under the drivers side motor mount on the front side. The right side circled plate required a significant bend at the top. The left side was pretty straight forward.
This is the front side passengers side motor mount. Pretty straight forward...odd shape but no bends
The next two pictures are the skid plate I made. I searched the internet and found pictures and measurements and duplicated it.
These next two pictures are the lower control arm reinforcement plates. Again very straight forward....just pay attention to where you will have to access with a socket at a later point and make sure the holes are big enough.
In all I had about an 8 hour day in fabricating everything up and welding. Cardboard was my friend...except when the templates caught fire from weld spatter. The only expenses I had were the time, weld wire and gas. Material was free because the 1/8" plate was freebie stuff I had laying around for years.
