I have small polishing mops and soap that will fit in there should i polish it to a mirror finish? Also could it be possible that there is an 88 sleeve in my 87 jug because I remember that the intake holes on the jug were a bit bigger the those on the sleeve. I haven't got my jug yet as I'm getting new studs put in it, cause the old ones were threaded bar and had streched. Also this is great info!
