I am not posting this because of price. Nor because this retailer is known to me.
I am posting this for identification numbers which this retailer has given for multiple casting id's.
It suggests they are interchangeable.
About a year or more ago I gave some info which was off by one number as it was unreadable on my casting.
I gave the number as 29786C WRONG!! It is 29785C .
Again, and more importantly, this url located below shows "many" and may be helpful to us Sweptys for interchange. Gordo
