Tranny life of a 80 3FE?

[RAM5500 CAMPERTHING]

the clunk is normal, nothing to worry about. the splines on the output shaft get worn and create slack(thud).

There used to be a fix for this called the McNamara Gear or something along though lines. Someone machines a new gear to fit over the worn splines and fix the clunk.
