Bobby... Yes, but in the breather box. Only the two hoses from the valve covers were needed. I installed two each, 6" long 1/4" pipe nipples into the back of the breather box. The reason for this is so I could detach the breather box from the firewall and pull the whole assembly out to clean and inspect the inside of the breather box occasionally. This way, I didn't have to crawl up in behind the firewall to detach those hoses from the breather box. (note that the breather box is mounted close to the top of the engine compartment). I drilled two holes in the firewall large enough to allow the hose clamps on those hoses to pass thru the firewall too. These holes are sealed with a high density foam ring around the 1/4" pipes to keep air and other things from entering the engine compartment except thru the air intake grill in the rear deck lid.
In my photos you can see the old breather hose elbows still in the air cleaner tops. Later I replaced those with a new, un-drilled set............Bruce
P.S. I don't know where I got those foam rings/grommets from. Just something I saved in my "Biz-Bag" ! (big box of junk you think you might need later ?)
