Re: [AMC-List] crossmember question & PARTING OUT 76 GREMLIN X

Hello:
 Can anyone tell me the difference in a V8 and 6 cylinder Engine
K-member in
a 1977 Hornet AMX?

Well, K-member eh? Actually Ray that I associate with a Chrysler term,
they actually use a K member. In AMC land that is usually just called a
cross member, or engine cross member. I'm not sure whether that is
opposite of a happy member or not though. Ok, bad joke. 
As the cross member serves to mount the end of the lower control arms
and performs two functions the two cross members are identical. With one
exception. The 6 cylinder cross member has 6 cylinder motor mounts
welded to it while the V8 cross member has 8 cylinder motor mounts
welded to it. 
To the best of my knowledge there are no separately available engine
mounts to weld on to a cross member although I think aftermarket may
have had them at one time or another. 
Thus the only way you can mount a V8 in your AMC car is to have a V8
cross member available. 
But BEWARE! 
I have heard of a number of occasions in the last couple of years where
our most famous trading store E-Bay and others have featured for sale a
questionable V8 cross member. All you have to do is bid some ridiculous
price for this part and then obtain engine mounts and weld them on to
the cross member. Remember, V8 engine mounts are made from unobtainium.
Also you can make your own questionable V8 cross member by removing the
6 cylinder cross member from a 6 cylinder I6 car and cut off the 6
cylinder engine mounts, grind everything smooth and then paint it. 
The end result is just as useful and a whole lot cheaper. 
To the best of my knowledge, Gremlin, Hornet, Concord and Spirit cross
members are interchangeable. 
I thought that I had reference to Javelin/AMX cross members as to
whether they interchanged too, but I can not find it. Maybe some one
else has this information. 
Good luck 
John.
