One new unused 33RS 105 and one new unused 33 RSF 105 that's a full skip just in case you didn't recognize the number. I sure could use a 25 and 28" full skip Stihl or cash. Make me an offer.
I'd be willing to make up some 84 and 91 or 93 dl loops of the Windsor, or if you want a picture of what it looks like, I can post one up.
I may have a 25" loop of 33RSF I used once or twice on my 361, before I got my 461, I'll see what I have lurking about
New off the reel.......50A on the left. New out of the box Stihl 33RSF on the right. Windsor 50A in front. Windsor 50A in front.
Oops, the only 33RSF I have is... wait for it... 105dl. You could always shorten your 105 dl down to 91dl, perhaps.(?)
Like Mike suggested, the easiest thing is probably to have a dealer shorten those loops for you. Make up a 28" loop out of the RSF and a 25" loop from the RS, probably for less than you'd pay in postage to ship those chains somewhere.
