I used this on my long gone 10" LX50. Made it easier to adjust for latitude and also stiffened the wedge considerably (viagra for your wedge!). May also fit 8" wedge, it is an aluminum shaft 1 inch in diameter, 8-5/16" long that bolts accross the inside of the wedge. Has centered 1/4" x 20 bolt holes in each end. Adjuster screw is stainless steel 5/16" x 18 and 5-3/4" long. beleive it was made by Scopetronix (Jordan Blessing). $15 shipped in USA. Paypal, MO, personal check (from excellent rated AMers only).
