Vivitar Series 1 28- 105mm Help

Hi All,
Can Any One Help Me, I Own A K10d, And One Of My Lenses Is A Vivitar 28-90, I Have Just Bought A Vivitar Series 1 28-105mm, Of Ebay In Germany, Not A Mark On It As New Even Straps And Booklet Remain Unopened, I Emailed Seller, And He Told Me Its Mount Was A K Mount , Couldnt Wait It Came Today And When I Looked At It I Couldnt Believe Its Condition, Mint,tried Putting It On K10d Very Gently, No Joy It Would Not Fit If Just For The Last Click, I Compared The Mount Code On Barrel And It Is Slightly Different To The 28-90mm.
The 28-90 Is Marked Thus P/k-a, And The 28-105 Is Marked Pk-a/r ??
Does Any One Have Any Ideas, Can I Obtain Any Sort Of Adapter?, I Dont Have Any Answer Or Idea, Hope Someone May Help, .
Many Thanks Kc

Sounds like an over-sized flange problem. My guess is that it's a Kiron-made Vivitar -- i.e., serial number begins with "22"?

There've been some posts here and at dpreview about how to fix this problem. Apparently an electric saw of some kind is required, which is beyond me. But if you know how to use such tools, it is supposedly an easy fix.
