Good evening all

Our oil pan was leaking and I had to take the engine out of our BFN 1994.
This was new to me and everything went pretty well. The oil pan came out easily and I'm sending it to a welder.
Decided to replace the damper plate and both of the seals while I'm at it. 

the question is that I can't seem to find the correct seal. On summit they dont have any reverse rotation rear seals, I emailed them and they said it doesn't matter left or right. Watching several youtube videos and reading on fora tells me there is indeed a difference. 
I also know that I have a 1-piece seal (1983-2001) and not a 2 piece seal. I read this somewhere on this forum. 

I have found 2 items on ebay and I want to know if these are the right ones (ones on skidim are overpriced and they charge a ridiculous amount of shipping)


edit: seems the one i posted earlier wasn't for reverse rotation. this one from Summit is RR.
Front seal alone:Fel pro 17795: https://www.summitracing.com/parts/fel-17795

Could you guys be so kind to confirm I have the right one? Smile

I could also need some advice in replacing them, so if you guys have any tips, let me know!

Thanks in advance

Your links didn't work, but here are a couple of links to EBAY, maybe the same ones you had 

link to rear main seal for Reverse rotation 351w   CS 4592RV

link to Reverse rotation front seal  FP 17795

Both of those seals will work for you

And here's a link to an old thread with some seal discussion and an alternate part number for the front seal SKF CR18562


PS......that 17760 seal that you mentioned fits a Chevy so I think I'd avoid that one. Wink

I seem to think that Gino is probably not exactly interested in your Skidim link and that's why he posted his questions in the first place
