Bent Main Frame Rail Below Slide - (Picture Heavy)

Hi John,

I know it's been awhile since you fixed you frame.
I had a question about the steel used for the sister plates, gussets.
Do you buy the same 70ksi rated steel to match up with the frame's steel as well as the 7018C welding rod?
I often read where a steel reinforcement is welded on, but no mention about the type of steel.

Any pictures of your repair?

Thanks

Gene
