Hello All,
I am working on the car in the subject. I went to purchase motor mounts on line and I found a "significant" number of negative reviews and discussions of them not fitting which shocked me. I am not sure what is going on here, some installations seem to have went great and others totally did not fit. I also saw some discussions on here about a tall and short mount, but they were old threads with broken links and I could not make sense of the topic.
I am doing significant chassis work in this area, and my intention is to build a light weight mock up of the engine and transmission so I can check fit from time to time. I do not have the original parts to compare against so I want to be sure I have the dimensionally correct parts.
The shop manual and chassis assembly manual only call out one assembly for this installation. This should be a straightforward issue. Are the reproduction parts just not consistent / accurate?
Should I try to find another vendor? or an OEM part?
I would hate to mock something up to the wrong dimensions. Can anyone offer any insight into this issue or advice? Much Thanks in advance.

1967 small block mounts have not been made for many years. There are none available other than originals. Most folks change out the frame mounts to 1968 versions so that is an option. To make the 1968 rubber isolators work you have to change the frame stands as well. 1967 frame stands and 1968 rubber isolators is why you see folks bad mouthing their supplier. That doesn't work!

Thank you - I figured that there had to be a reason. So question: If I buy reproduction 1967 motor mounts is that what I am getting or are they 1968 motor mounts mislabeled? Is there a definite way to tell? Drawing or Dimension?

Fair number of prior threads on the issue. Found them by just using the words "67 motor mounts" so there are likely even more
Just a few below. Not much has changed in other ten years

No one is making a reproduction 1967 engine isolator mount. They have not been made for many years. If someone is calling them that they are mistaken.

If this is not a car that you show or one that you are more concerned about functional instead of what is correct you may want to consider the 68 up chassis mount and motor mount alternative. A nice show worthy set of correct 67 motor mounts might set you back 250.00 or so. If you want the correct part you can PM me because I know someone who has some. ;)

Okay, so I think I got a handle on this, but getting confirmation is difficult. The parts suppliers simply do not know the minutia of these details.
So a set of aftermarket frame side mounts is listed as fitting 1965 to 70 and the motor mounts are listed as 1965 to 72.
It appears only the 1967 factory frame side hardware is unique.
If I just purchase the aftermarket frame side brackets and motor mounts it will fit my car and the motor will sit correctly in the chassis. At least that is what I am thinking. If it weren't for the fact I am doing major reconstructive work in this frame rail and shock tower area I would just put it in and take some measurements, but I'll be placing the shock towers based on a mock up of the engine and transmission with these as connecting parts. I'd like to know before I start fixing parts permanently.
Does the above logic sound reasonable enough? Is anyone out there with first hand experience that can offer any advice?
PS I am not being that particular about being correct.

Only 1968 small block frame mounts will work with new rubber isolators.

Thank you Royce,
But If I want to buy frame side mounts they are listed as fitting as 1965 to 1970 mustang. Does that mean that those aftermarket frame side kits are the same for the '68 as you point out? That's my question.
It appears that there are several different versions of "factory" parts for this period. I don't just want to assume that the aftermarket suppliers settled on the one variant that fits all of those models in-between. I am hoping to get a confirmation of that assumption.

I have not used the repro frame mounts but expect them to be deficient in some way or the other. I would buy 68-70 used if it were me. OEM parts will fit better for sure. Yes the aftermarket suppliers settled on the one variant that fits all of those models in-between.

I don't know what you would get. I would just buy factory 1968 parts. Reproduction stuff usually doesn't fit or work right. [/quote]

Allright,
Keep it pure - I get it! So where would be the best place to find Factory 1968 frame side mounts and Engine mounts? Or factory parts for that matter? All I know of is the reproduction stuff....

eBay has them, or WCCC.

Don't forget that the rubber insulators are different too.
