New Handles for Straps

I always wanted to add these two handles for the strap to hold my feet down when I did Sissy Squats, but never had the steel until I got the bike parts. But then I forgot I even had this frame, as I never do heavy legs in the summer & this was in the spare bedroom.
The strap normally goes underneath the Tbar row frame but when it's all set up & the strap isn't centered right, I have to lift the entire frame(65+lbs) with one hand & readjust the strap. No more. Now the straps can go on any time perfectly.
