Fitment help needed
I have started a custom build, and decided I want to go another direction. Rather than finish the custom, I want to use my drive line in a stock bike. So the problem I am having is knowing what my drive line will fit into.
Attached is a pic of my custom. The drive line I have is a Revtech 100" with a 6 speed tranny. This is the 100" Revtech motor before Revtech came out with the 4x4 100".
I would like to place this drive line in a older FLH bike, now i realize the 6 speed tranny may need an adapter plate welded in for fitment due to the 5 stud mount. I really need to know that the motor will fit into the older EVO chassis.
As an example, I am looking at this 1986 FLH as a candidate, pic attached. If I had a choice 1995 would be the perfect year FLH to choose, because that model was basicly the same for quite some time before that to my knowledge.
For some reason my pics will not load, will try again later

The best place to find that info is RevTech. Their engine and trans will be made to fit certain styles of frame and that sort of info is probably with the instructions you should have, that came with them both. If you were using a custom frame, that will also have been designed and made to suit a specific engine/trans build, so that also should have paperwork recommending what to use. Assuming what you have is Evo, they will probably fit either a touring or softail frame, possibly FXR or Dyna, but year range is also important! What type of primary drive are you using, as that is a further clue.

Fitment
Ok,
now that I have figured out how to upload an image, the first 2 pics are my custom and the last pic is a 1986 FLH that could be a candidate for my drive line.
My custom frame is a Ultima softail, +2 up and +2 out, with an oil bath primary. I do not recall getting any information with my drive line as to what it's fitment is, I honestly thought it was just a standard EVO replacement drive line. But it seems to me that the Ultima frame was specified to 1999 in years. So maybe that is the answer, whatever the EVO years were that ended in 1999 (from xxxx to 1999) ? I think this is what I need to know. Even if the bolt pattern is correct I am concerned with the height of the motor as well, it is 100" and I do not know if it is taller than a stock EVO.
BTW, part of the reason I decided to not finish this custom is the quality of the Ultima frame. And I kinda think it would be cool to have an older FLH with a new drive line to start. That 1986 FLH I am looking at seems light for a full dresser.

Ok I did some sleuthing,
what I have is a 2005 Revtech 100" (not the 4x4) drive line, generation 2 motor. My frame is 1992-1999 and the drive line is set in it per pics above. So my concerns are now 2 things:
1. is this replacement EVO motor an exact fit replacement (fits stock frames)
2. which years are going to be a direct bolt in for sure (earlier than 1992?)
I purchased this from Ardmore, Oklahoma but I cannot remember the name of the company (J&P perhaps?).
From the reading I had done on the web, the first generation Revtech's are said to be junk and the third generation the best. Well, I'm in the middle. At the time of purchase I remember reading that both Revtech and S&S both had their share of problems. That's neither here nor there now, what I got is what I got.

To complete your custom frame installation you would need a softail primary, which is longer than a touring one, due to that frame tube that comes down between the engine and trans casings. That feature replicates the style of pre-Evo touring frames. To fit a touring bike you will need the shorter primary.
It is very possible you can do that, but I am going to suggest you post again in the Evo section, where you will find several experts with better detailed knowledge than me! I'm sure someone over there can give you clear advice.
