broke? lol. i forgot to mention that i used this tape to cover the holes. it looks like aluminum tape. i always use it when installing heater and a/c ducts in peoples houses. its kinda thick and moldable. maybe if your box is cracked it can hold it together. the adhesive doesnt get soft when heat goes through the ducts.
i removed the a/c shit inside that black box, jb welded the holes shut that were a/c related, everything works fine, The black box hardly weighs anything, used the existing rubber grommet through the firewall and ran a power cable for my relocated battery. nearly fills the entire hole, as for the grommets small hole, ran a few other wires for some other miscelleanous things. all in all, works pretty well.
i could be totally off from the subject…but thats what i did
