Sorry I am too late for this discussion and probably asking something out of the box but it's very important for me to know this. Will appreciate any suggestions on this. So basically I recently bought have a 1994 F2 and the previous owner has installed an aftermarket shock which bottoms and hits hard whenever I run over small potholes and even speed breakers and other uneven patches. I researched a lot and I'm confused between MV9-661 (stock) & MAL-601 (F3 shock).That does not look like the correct one to me, the shock body looks to narrow compared to the resevoirr.
Ask the sell for the number on the shock it is on a yellow sticker near the mount. It says SHOWA and then has a part number below it. ( you can see the sticker in the pic)
My MAL-601 looks just like that one, the MV9-661 on the way has a much fatter shock body.
