I need help... motor mounts

[Ross302]

I am new to the site, my cousin turned me on to it. I have a 81 notch and am trying to put a 90 5.0 in. I had the entire motor with t5 attached and hanging in the car by chain. The bolts on the mount did not line up to the hole in the k member...

There is a single hole towards the back of the k member and a oval/wedge hole towards the front of the k member.

Which hole does the mount go into? And does any one know what motor mount to use?

This is the second set of mounts I picked up at the parts store. The ones i have now are for a 93 5.0 convertable.

any help would be greatly appreciated.

You may need to get motor mounts for an '81 . I thought that the V8 K members were the same 79-93. I'm sure someone here knows for sure.

did the car have a 6 banger in it before if it did u need another k member. my friend had a 79 and it had a 6 banger in it and he had to install a v8 kemeber

My sisters had a 6 in her 83 too.. Could need a new k. Not positive thought.

It had the v8 4.2. the 93 motor mounts I tryed seemed like they would fit, however the "Boss" pin on the mount did not line up in the hole on the k member. I went to the parts store to see if the 81 mounts had that pin in the right location, but they did not have any in stock. I am hoping there is a difference in the pin location on the 81 mounts and they have the same alignment to the block as the 90. That is if the block of the 4.2 and 5.0 have the same set up for mount mount palcement.

If it's just the pin stopping it from seating, you can either drill a hole in the k member to line it up or grind the pin off. The k members are very similar 79 - 93, but not identical. you should be able to make it work; however, for about 250$ you could buy a qa1 k member and save some weight and make some more room at the same time.

If I grind the pin off, will that cause any problems down the road?
I think I like this idea the best
Thanks for the advise.

American Muscle list mounts as the same for 84-95, and LMR 83-95. There must be a difference in the mount/pin location on the K-member for earlier models.

So let's see some pics of the motor installed.
