K Frame stiffening plates - Who has installed them? Any pitfalls or recommendations

What were you doing here Elk? Alignment tool to make sure the hole is still open?

What is it?

That's what it looks like, and a damn fine idea!!

Just a pivot shaft set in place after grinding to be sure it sits flat and still goes into place.
 
that's a nice clean job there :headbang:
 
I spent a weekend cutting metal and welding to gusset up the K-frame, make a hemi style skidplate and making LCA stiffening plates. While at it I seam welded the entire K-frame. I haven't put it into the car yet, but I had fun doing it and it looks cool sitting on the floor waiting for the engine to get installed.

I'm also going with the 11/16 tie rod ends and the PST adjusting sleeve but sticking with the factory manual steering box with the long steering and pitman arms.

I had as far as the gusseting and skid plate....I had all the material laying around so all I was out was time. The trick is to make all your templates out of cardboard first to get the fit right.

Hey dsd1967 can you show some photo's of what you did? Did you do any additional gussets beyond what came with the kit elk used? If so where and how does it look?

I called the welder so I'm set for him to do it as soon as I get the parts. I'll show him this thread for examples of what elk did and yours if you took pictures. If it's in another thread already shoot me the link please.

I'm also interested in any feedback if someone is using a Firm Feel II sector and is NOT happy with how stiff it is and wished they had went with a FF I box. So far all I've heard is positive but I'm wondering if the FF II will be too stiff / tight for me since I haven't driven a car with that unit. Only drove stock Diplomat cop cars my Dad used to have.

I'd also like to hear some feedback incl negative on the fast ratio idler and pitman arms. Good idea / not a good idea for daily driver big block b body with the Firm Feel box. Are the fast ratio arms too much ??
 
Thanks for the PM DSD I hope everything worked out Ok with the job today. Looking forward to the pictures!
 
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.

3.JPG

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

4.JPG

This is a plate under the passengers side motor mount on the back side of the k frame. Odd shape and required a bend.

5.JPG

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.
 
Excellent reinforcing there Dave that looks very sturdy now!

Thanks for the pictures which are worth a 1,000 words as they say!
 
Damn I wish I had done some reinforcements on mine before I put it in, very cool thread and thanks to everyone for sharing the pics

Concur Mr SF. There is a lot of great how-to and examples. Thanks to Cranky, hunt2elk, and dsd1967 for sharing your work via pictures. If anyone has any further examples or different ideas on the strengthening please share the photo's and description of what and why you did.

And this from Ebooger. I'm looking at that too over at FF by the way but will be later if at all. Rick says do it instead here in the same thread:
