I picked up a set of the newer style, bolt-thru motor mounts for my 65 FB. I'm replacing the older stud type mm. They don't fit!!!. The old ones are attached to the body by three bolts. The new ones use only two bolts. The only way they can attach with the existing holes, is if I use the two innermost holes that are lined up one over the other. But when attached this way, they are turned down to far and don't line up at all with the insulator on the block. When I try to bolt the new mm using the other bolt hole that is more out toward the shock tower and the bottom hole of the two inner holes, the outer hole is about 1/2 in off from the whole in the bracket. I can't rotate it any farther because of interference of a protrubing tab on the bracket with the body. This may sound confusing to you, so please post any ? that may help for me to explain this better. I've checked all my catalogs, but can't find the right picture angle to point out the "tab" or part that is causing the interference.

Here is a picture of my passenger side mount from the front. I had 65 mount and changed them to the 66 style as well.. It was a big improvement.

From that angle, it looks like the mount I'm trying to use. When I have that bottom bolt in, and rotate the bracket to the left to line up the other hole, it doesn't line up. About a 1/4 off. Further rotation is stopped by a tab like part interfering with the body, which can't be seen in your pic. Thanks for the pic. Maybe someone has some ideas of the problem.

Did you change the insulator on the block as well as changing the motor mount itself, as they use different insulators ?
Don't mean to sound stupid or insult your intelegence, just considering all possibilities.

Hi Joe, this conversion really should be easy. I converted my mounts last year and had no problems at all so I do know they newer mounts do go in without any problems. I hope you problem is so simple you just aren't seeing it.

Good luck....

I am also doing this exact same swap and ran into the same problem. Does anyone have a picture or drawing from the service manual that might shed some light on this. My 65 manual only covers the ones I am removing.

I'm in the same boat. My shop manual (65) is no help. Today I'm going to show the mounts to a local expert and expect I'll have an answer later in the day. I'll post it then. My motor is already back in with the original mounts. I've never had a problem with them in the past and was just attempting the swap because I got a smoke'n deal on the 66's. So I'll either save them or sell them.

I ran into the same problem when I took a set of the dog-eared mounts off a '67 Mustang. As is turns out, they were big block mounts and would not line up with the small block insulators.

Any luck, mine has an R stamped on one so I assume it is the passenger side but to I have to pull out the center cross member to get it to line up in the two vertical holes, also it is probably a 1/4 inch off of lining up with the hole that is horizonatally offset. However, it seems to line up when I reverse them but I am confused. If someone could tell us if the secondary piece that has the short bolt goes to the front or to the back I think we could figure this out.

Sorry I didn't update. Found out I have 68 mm. Apparently the only ones that will fit the 64.5-66 are the late 65 and 66. I just kept the old ones for now and will try again when I'm sure I have late 65 or 66. I'm guessing that the aftermarket repops can be used from 64.5 up to 70 with no problem (other than $125) but the Ford OEM stuff is only good for 64.5-66.

Paul, I found a set of 67- 289 mounting brackets and when I put them in with the two bolts to the frame going through the vertical frame holes I get in the way of my cross member. I have loosend up the cross member and been able to get all the bolts in but when I tighten everything back up they will at the least be in direct contact with each other. Is this normal? I am concerned about a vibration problem. Also, they seem to fit great when I reverse them and put the offset end of the bracket to the front but I think this is the wrong way especially since that would put the one with the letter "R" stamped on it on the driver side.

Chris, I am also in the middle of this on my 65 fastback.

I would appreciate any help.

You've got me there... I did not think the 67's would work.. I have the 66 style on mine. Don't know if I can be of much help. Sorry.
