small block engine mounts question

[74fldart]

is there a difference in the 318 and 340 , 360 engine mounts? i have these 2 mounts and need to know what motor they fit. i do understand they are late model spool type. thanks

340 & 360 are the same, the 318 is different. I believe the RHS on the 318 is in a slightly different position than the 340/360's

driver side enginemount ears on block is spaced wider apart on 318.s 318mounts work on 340and 360 with just a nut as a spacer...

hmm those mounts seems to miss the tube that the rubbermounts are pressed into

Kind of weird that they have "***" stamped into it at the end of the part number!!

Hopefully that is shorthand for "Assembly" or some UAW folks were screwing around that day
