Clint Fowler Op Rod Guide Pics?

[JJM1]

Does anyone happen to have any pictures of the mysterious Clint Fowler Op Rod Guide? It's part of what he used to do to accurize the M1 Garand. I have a written description ("The guide system had to be two pieces. The forward piece a circular track epoxyed in the upper hand guard and a lower track silver soldered in the stock ferrule. Both had to be fitted just right. They could not bind the op-rod, but they had to almost touch it, a light slide fit."), but pics would really help...
