Due to the reduction in slop the lower bushing on the shifter is designed slightly larger than stock. This is to take up any variances in the stock bushing seat. If it does not fit, slightly sand the outside of the ISR bushing until it is a very snug fit.
Finally a Solid/Short Shifter available in the US for the RB25DET!!!
