Just took apart a very original 1929 DL motor which has a badly bent forked rod. Apparently these pre late 1932 rods are difficult to find. I know the 1929 rod is 5/16" shorter than the 1932 and up rod. Also, these 1929-early 1931 rods have no wrist pin bushings and this area of the non-bushed rods has wear. Is there a way to use 1932 and later longer rods in this motor, such as a piston with different wrist pin offset. Only other way to use late model longer rods, I believe, would to be change out to later 1932 and up complete top end. I had rather keep the original top end which is in good shape if possible. Or does anyone know of a possible source the shorter 1929-31 DL rod? Thanks.

But if it isn't a kink that produced stress-risers, (Magnafluxing prudent..)
Then you may have little choice but to straighten them.
