Im looking to get some Password JDM engine dress up parts for under the hood and I was wondering if 6Mx20 will fit in bolt holes under the hood.

Also, by chance is the first gen xB battery tie down the same length as the the second gen tC's battery tie down?
I know its kind of random but Password JDM sells an aftermarket battery
tie down and I think it will fit my gen 2 tC. Here is the link.
