Eagle use to make an I-Beam rod part number SIR6125JB and currently make an H-Beam rod part number CRS6150A3d.
If anyone has a gently used or like new pair they would like to sell please send me a PM.
Thanks

AMC 304-360 rods should be close enough in the eagle catalog

The 304/360 rods are the same casting, but the 258 rods are narrower. If you used the 304/360 rods in a 258 the rod end clearance would be too wide...bleeding off too much oil.

The 6 cyl rod big ends are wider.
