G704 engine parts

[T Wall]

I'm doing some engine work on a local farmers 1963 G704. Where is the best place to get parts for this unit?
Piston rings, gasket set, bearings, etc.
Thanks

G704 has same motor parts as GBD GV1 or U diesel. I rebuilt my 704. I have some parts but in Canada. Welter in US.

Rings are NLA for the 4-1/4" bore diesels. Welter's were able to get me a custom set but they were expensive.

Have few sets in stock.

I've decided to bore it out to 4-5/8 and go that route. I did that on a UTSD I went through a number of years ago and it works well.
Thanks

My G704 was 4 3/4 but went back to 4 1/4 as wanted original.
