Adjustable Strut Rods

my 2 cents.

1" tube is really too large. Use 7/8" and if you can find it in .159. Then you can tap the ID directly for a 5/8-18 thread. I'm going to build my own and will likely use a 7/8 DOM tube.

Use a 5/8 shank, 1/2" eye heim, you'll have space limitations where the heim is located in your K frame.

Look around at your competition in this. One of the better kit is Reilly Motorsports and it's about $199.
