How big an end?
Was looking at one for 350, (on sale at 300) yesterday, with a 3/8 end o r 8mm.. it should get in a sparkplug hole. It had a mirror attachment, that clips on and can be turned.. like 1/2 a periscope..
I am trying to get one for next spring.. can do gas tank inspections at a swapmeet...should help pay for it...
