My daily driver is a 1985 FLHTC that I purchased back in 1992. In 2002 I purchased a FLHTC and had a Lehman trike kit installed so I now have the swingarm from my 2002 and was wondering if it would fit on my 1985 FLHTC. This way I can upgrade to the larger axle and better brake that the brake on my 85.

 

I put a 05 swingarm on my 94 with great results and benefits....better brakes, bigger axle in both the wheels and swingarm pivot , wider selection of wheels,.There was the modification to the transmission pivot shaft hole stock was .630'' bored out to .750''
The other stuff was just over the counter HD parts..

The kit in the above article is way cheaper to purchase than the parts from the HD dealer. You will have to purchase the end caps as the early models such as yours and mine won't work with the new style isolators.
