I just replaced my trunk struts on 2001 Ultra model . Now keep in mind I am a chef not a mechanic . Was frustrated for about 2 minutes then had my wife lift up on the trunk lid , hyper-extending it , until the strut just snapped into place . Took about 5 more minutes to replace both of them . Hope this helps .
Bought mine on e-bay as well
I just replaced mine on 1999 SC400 and used the hyper-extending method also and they then fell right in place. Bought mine from partsgeek.com
When I replaced just one strut (they insist you replace them in pairs - I guess to load balance?) it was just perfect. When you placed pressure on the lid up or down it moved with the easiest touch.
When I replaced both it tended to spring up and require undue force to close it.
FWIW I think I paid $38 a pair on eBay.

My trunk was difficult to open and I check with my dealership and they were $270 for a pair. I went on eBay and bought them for $45. They fit to a T and they are working perfectly. Below is the eBayer that I bought them from.
