F.Y.I. Motor Mounts

Is that for a slant or a 273? If you are talking about slant mounts this company has a good rep. I have heard that the pass side mount is slightly (1/8") shorter than factory. And they are made of polyurethane so a leaking valve cover will not destroy them and they are an explosion/failure proof interlocking design.
