63-66 idler arm conversion to late model thru bolt ?

I think I will look in my shed in the morning for a late model idler and compare them . If the dimensions are the same I will jig and mod the K member for it .. I figure I would ask . I'm too tired lazy to go out to my shed right now . LOL. Thanks

Why? Plenty strong as is. Have put 500K miles on those cars, 64 66 and 67. Idler has never been a problem. 140 mph and all
