Hey I'm can't make a final decision with my rear shocks. I'm looking at either Tokico Blacks or Gen 4 Bilstein 5160s (25-227611) to match my Dobinsons 210V rear coils. I know that in order to fit the Tokicos I will need to drill out a larger hole at the top shock mount (11/16" to 15/16" diameter). But if I drill out a larger hole for the Tokicos will that mean I will have trouble using other shocks in the future? Like if I want to switch to the 5160s sometime later, won't the top mount have too much play due to the oversized hole? Or do the bushings and retainers keep the shock from shifting at the top? I know this is probably a simple concept, but for some reason it is causing me a lot of confusion. Thank you.
