front top hat replacement

[Jvan]

Last year I installed the AMR coil overs and have been very satisfied but I problem has developed that is not with the coil overs but is affecting how they work. The OEM rubber top hats have deteriorated to the point that they are barly holding the top of the coil overs. They need to be replaced immediately but I'm looking for top hats that will compliment the coil overs and not just OEM replacements. I looked at early STI Group N top hats but the spacing of the top bolts is different; anyone have a recommendation for an aftermarket top hat that can help the coil over perform to their best? Do you think drilling new holes in the support to fit the STI top hats would be advisable or would it weaken the support; what if I welded a bolt into the old holes?
