Help please! Last week I installed the 390 into my '66 Fairlane. I put new (Korean made) motor mounts from Auto Krafters. Well the engine now is sitting about an inch forward too far. The old marks are evident in the trans crossmember from the washers, the humps in the tranny cooler lines that go up and over the sway bar are about an inch forward and the fan is way too close to the radiator when I went to drop it in. When I replaced the motor mount isolators I did them one at a time and the two were never off at the same time so I'm pretty certain the intermediate support bracket (upper half of steel mount) is on the correct side. Just to be certain, can anyone verify for me where the cutout or notch is on their motor mounts, this is the notch that provides clearance to the nut on the isolator. Is it pointed to the front or rear of the engine? See page 8-86 of the '66 Fairlane factory service manual. If I do have the mounts on correctly then it appears the isolator has the mounting stud molded in the wrong location? Has anyone ever had this dilema? A picture of your motor mount installed would be helpful. I do have the isolators located correctly. Auto Krafter p/n 2240 is RH and 2241 is LH.Thanks,

It would appear that you have the mounts inverted or they are made that way.
Assuming that you still have the engine hoist near by, can you lift the motor up just enough to remove the mounts and swap them from side to side?------------------

I have the mounts oriented the same as the shop manual shows? Maybe I need to loosen all of the bolts and shimmy and shake the engine and see if it settles in it's mounts better?------------------

It's been a while since I've been in a '66 - '69 big block engine bay. Can the rubber mounts be reversed? I remember you have a total of three pieces on each side. I don't think the two metal pieces can be reversed.Tracy

It's not possible to install the isolator part on the wrong side. It's too tough to explain but as soon as you look at it you can tell.Thanks, ------------------

Not sure if the car was a 390 car originally or not or if that matters. Do you still have the old mounts to compare them? I think on a Mustang it is possible to mix them up but it?s been 15 years since I had the engine out of the fastback. Have you talked to someone at Auto Krafters? ------------------

I took all of the mounts and isolators back out on Sunday and tried to install them wrong. You can only install the isolator one way and on one side will it fit, the same for the intermediate mount. With it's angle and stud location, there is only one way it will fit. I tried every combination to screw it up and it won't. I reassembled everything the same way I had it. Now I'm only about 1/2" too far forward. I lifted the engine and had all of the bolts loose so when I was lowering the engine and shaking the heck out of it, the thing must have settled better this time and is sitting back further. The old mounts were twisted somewhat, including the tranny mount. Maybe over 39 years the original mounts twisted and moved around somewhat. With the location everything is at now, maybe is due to new parts? This is the original engine and mounts. I didn't call Auto Krafters, they don't speak Korean, they just sell it:-)

So I take it that AutoKrafters sells the four (two per side) steel pieces? They might have have had a bad one to use for a template.I would let them know about it. Tracy

No, Auto Krafters sells only the rubber isolator. The four steel pieces are original.------------------

Have you tried Auto Zone, Advance Auto and O'Reilly's?That rubber mount is the same for 390's and 428's from 1966 through 1969 Fairlane's, Torino's, Montego's and Cyclone's. Tracy [This message has been edited by DidgeyTrucker (edited 04-16-2005).]

The Autozone mount has exactly the same Korean markings as my AK mount. The engine is in and I'm satisfied, not extremely but satisfied that I have it installed fairly decent.------------------
