Thanks, Downunder!

I checked the site again and am still somewhat unsure.....although your post gives me confidence.

Here's what they list:

16745 - 61 FSR ABC
16770 - 61 FSR
17700 - 61 SF Ring
17702 - 61 SF
17710 - 61 SF-P Ring
17712 - 61 SF-P
17801 - 61 RF
17802 - 61 RF-P

Now, if the FSR stood for "Front intake/side exhaust/ring", there are more than one to choose from in this list, yes?

I am unable to find a picture of it, just a parts listing.

So we know it's not an ABC, and another gentlemen stated it's not an SF, so the fickle-finger points vaguely to a 61 FSR.

I really feel you are correct, Downunder from Oz.

Any dedicated, died-in-the-wool O.S. men want to corroborate?

(Thanks again Downunder!)
