sorry but those look wrong to me, the new ones I bought have the external boot, those are more inernal boot type and use little pushers on the ends to make them reach the brakes. I saw they are the wrong ones and won't work. They had 3 listed for my 88, 1 inch 1-1/8 and 1-3/16. I measured and mine shows 1-3/16 bores on the inside, but some were listed as internal boots and external boots online. Mine were external like your old ones and the ones I put on had the same type boot looked exactly the same as your old one. Only ones I ever say like your new one had pushers or little feet to come over and rest on the shoes, and had a small dia. hole in the middle of the rubber boot for the other end to fit in, slightly bigger then a pencil dia. These like your old ones are more nickle sized or close to quarter sized maybe.
