I've been reading a lot on replacing the rear struts on my 2006 Limited with 290k miles. KYB Gas-a-Just seems to get the top billing for the rear, with Ultra SR for the front. Sounds great. The only problem is that there seems to MANY model numbers for the GaJ, and AutoZone doesn't list any of them as compatible with my Rav. Which model number should I look for both the GaJ and Ultra SR? Thanks!
