Hey Todd,

Just a little product feedback. I got my BHS511 motor mounts and 71222024HKR Crossmember today. Everything fits great. The only thing strange is the bolts provided for the motor mounts have a very small head. I'm not using them anyway but they are definitely not appropriate for the job. I do appreciate the flange nut and bolt, but the flange on the 3/8-16 x 1 bolts is too small.

I appreciate you taking the time to provide your feedback. I'm going to have someone look into the specific hardware as I don't believe that is what is called for on the BOM for those brackets. Update: I've confirmed that the type of bolts packaged with the kit you received are not what was intended to be used by Holley engineering and the supplier has been notified that a correction is needed on future production runs.

My engine stand kit came with the same bolts. Will source 3/8-16x1 grade 8 replacements and use washers. I think it would dangerous to use the bolts as supplied.

For those who have installed the kit, does the taller extension pipe between the H pipe and muffler go on the driver or passenger side? The instructions say there is a notch on the drivers side extension, but I don't see it.

Thanks!

Meant to quote this post...

Also, forgot to mention, one bolt was smaller than all the rest (5/16")
