David, I initially ordered 2-3 cheap springs, BDL, ADL(?), and one for a Ruger.
The BDL worked the best but I'd have to dig through the 'parts bag' to see if I tried an ADL.
Ted, same deal here. There is also a bag of front action screws in the 'parts bag'.....grin
The one and only time I contacted Kimber was a phone call to Kalispell, MT(?).
Really nice lady, the part(a replacement mag spring for an 84L..........) was out of stock.
