Rubber grommets for remote reservoir shock - body pass through?

[Elombard]

I see places like jegs sell a 3" with a 3/8 hole - which would be perfect except not sure the remote reservoir body will squeeze through the 3/8" hole. I also see split seals but they are like $40 each!!! What are you guys using? Any low cost options?

Also love to see where you are drilling the hole to pass through Front inner fender and rear fire wall. I think I know but I only want to drill one hole :-)

thx
