These dimensions will work for most any application if you can tell which cross sill or rear sill holes the bed strips go in. http://www.mar-k.com/bedwood_dimensions.pdf The critical dimension is the raised part of the wood that goes between the strips. If it is too tight, it won't allow for expansion or for buildup of the finish material. If you only use the overall board width, slight variance in the groove dimension will make the board too tight or too loose.
