Thank you!

Checked out the website and unfortunately the only parts listed are the timing cover itself and I obviously don't want to buy a timing cover in order to get some new o-rings. Good suggestion tho, I appreciate it!
At any rate, I have the part number for the crank seal and I think I have the proper number for the coolant connection (#4). I also have a part number for what is referred to as the Crankcase O-Ring but am unsure if this is #1 or #2 (I haven't measured them but I believe that #'s 2 & 3 are the same size). Might just order one of the part numbers that is referred to as the Crankcase O-Ring and see what I get.
If anyone else can chime in I'd certainly appreciate it. If I figure out anything, I'll post it here. Thanks again!

…if you have the O ring in hand take it to auto parts store and they can matched for you given the thickness and diameter…
…knowing that I can give you AN/MS but the parts store is quicker

Ok, I have part number updates for anyone that may need this for a future project. Couldn’t find a Smart part number for #1 but an O-ring with dimensions 1 1/2” ID x 1 11/16” OD x 3/32” wall is about as close as you can get, BrassCraft #SC0606. #’s 2 & 3 are the same, Smart # A0219970645. The coolant hose connection, #4 is Smart #A0199972945. Not marked on the photo but may be helpful is the cranks shaft seal, Smart #A1320320080.

In addition, if you’re OC like me and want to replace now while you’re in deep, here are a couple other part numbers for the project, sorry if this is a duplicate from the part number sticky. The seals between the spark plug cylinders to the valve cover are Smart #A1320150080, you’ll need three of course. The alternator/water pump belt is Gates #K040315 and the A/C belt is K040289SF. Most of the other parts were fairly easy to identify. Good luck to everyone that’s diving into this work!
