79 camaro subframe repair plates ?

I have a 79 camaro that I need to patch/replace the body mount plates on the subframe. The only kit I found was for first Gen. and I am wondering if I can use that kit or is there someone who makes a kit for the second Gen camaros ?  Or should I just make them myself ?
 
Thanks

If you can , just make them yourself . I havnt seen much for 2nd gen frame repair.
