I built two ajustable threaded 3/8 fore and aft struts for the 505 I have in my barracuda , but haven`t needed them due to lack of traction !
Much like the ones in the pic above, but a little simpler and liter------
I am glad you said 3/8. The ones we made up are also 3/8 and I was concerned that the size was a little on the small side.
I guess they will be ok. S&w sells a chrome moly kit that is 3/8 as well.
