Thanks for the responses!
Dan, will do as suggested, utilizing your links - and thanks for pointing out the missing and incorrectly assembled parts. (I tend to too easily trust that whoever did something before did it correctly!)
Nick please note that I edited my earlier reply (lined through a couple sentences) as my observation initially was incorrect. I didn't have my tri-focals on and missed some details.
It looks like you have everything there you need and it's in the right places.
