Rear main seal install question.

Hey guys I am about to install a Fel Pro Viton (orange) side strip seal on my 68 383. I am replacing due to my last seal leaking.. I have engine out of car on my engine stand and upside down. My question is where exactly due I put the black RTV sealant and do I install the seal retainer with the side strips installed in retainer as one, or push the strips in after the retainer is in place? And I also will be installing seal "offset" Any tips or info would be appreciated. .. thanks
