All .75 fifth gears fit a 4k?

[rfkellner at snet.net (Rick Kellner)]

I realize it will be a long stretch between 4th and 5th however it may
meet my needs/plans.  I was also thinking that the .75 was so prevalent
that it would be easier to locate one.  A .80 might be a better
alternative however they do not seem to be as plentiful.
I like the close ratio and high final drive ratio of the 4k for
acceleration and general running around the twisty roads and hills where
I live.  I want the tall 5th for cruising on the highway which will keep
my RPMs down and the fuel economy up, but yes, a .80 might be better.  
I plan on bolting the 4K to a 2.0l bottom end and a ported 2.0l head,
header, cams, etc.
 
So does anyone have a 4K 2.0l with a fifth other than the .89?  How is
it on the highway?
 
Other than the FF, which I did not have on my list below, are the other
.75 from 020 boxes all plug and play?
Thanks, Rick.

You can get the .75 from an FF and it will transfer to the 4k.
Weird combo, really short 1-4 then the stretch to 5th. Whacha building
Rick?
