Need help. I split a motor mount in my 69 convertible - 351w.
I bought replacement mounts from a parts store that amazingly had them in stock- Duralast 2257 made in India. Same product number for L/R. Driver side in no problem, no luck fitting passenger side.
The production look and bolt holes, were identical to each other but not to originals.
I ordered L/R motor mounts from Anchor, made in USA. PRoduction looked much closer to OEM. Although 5ey specified L/R, they are the same part number 2257.
Same issue.
The part number from the originals - C7TZ6038E indicate it is for a 1967 small block. Further websites indicate it is NOT FOR CONVERTIBLES.
Thoughts on how to proceed are greatly appreciated
In order to use reproduction SBF engine mounts, you would have to change your engine frame stands to the 1968-70 small block, hard top style.
1967 owners with 289 engines have the same problem.
The good news is that the frame stands that came in your convertible, can be sold to guys with 390 or 428CJ.
It may not be that easy. If you change the frame stand that will change the height of the engine- trans. You could end up with exhaust clearance issue in the tunnel. The pipes may hit the convertible cross member plate.
I had this problem with a 69 XR7 convertible. When I swapped the original frame mounts for small block ones, it shifted the engine/transmission about 3/16 of an inch. To handle this, I had to adjust the shifter linkage. There were no other fitment or clearance issues
maybe this has been answered previously, but what is the difference between a 69 hardtop motor mount and a 69 convertible motor mount? particularly for a 351W car?
You need the hard top “ENGINE PEDESTAL / FRAME BRACKET” and then the available insulator(what most call the motor mount) will work. The pictures I posted earlier are showing the deference in the 2 types.
Hold on to your '67 or convertible engine stands (I did) for when the above event takes place.
I replaced the engine stands/isolator on my '67 w/'68 spec parts from WCCC. Thanks Don, the engine stands looked brand new after a bath in the parts washer & a soak in Evapo-rust: factory paint daubs & everything.
I replaced a motor mount on my 69 convert,with a std insulator- mount, with no fitment issues, does this imply the previous owner has previously changed to the upgraded bracket ?
