No, the instructions did not say there was no instructions but when I called Mancini and talk to them, he said some guys put attack on them and some guys don’t

I would not tack weld end in. You are creating a failure point.

Let me ask you this. Where can the end go IF by some queer chance the end gets loose? It’s captured.

If I counted up all the 3 piece pushrods I’ve used since 1980 the number would be staggering.

And never has I seen an end get loose and fail. Not a one.

I would suggest not doing that any more.
