I should have been MORE specific...these 2.5 lb. Halon bottles COME from Sean Roe WITH a CUSTOM bracket( that HE makes ) that allows you to mount them using the front the two front seat mounting bolts on the passenger seat. The bolts can be removed with a 13mm wrench, slip in the bracket, return bolts to original holes, and you are set. So far, I have placed them in Gen I RT/10 ( HARDER to get to bolts as the seat is more forward on mounts...EVEN with seat ALL the way back ), ACR ( EASY, but you MIGHT want longer bracket arms to allow clearance for anti-sub. belt mount in floor ), and 97 GTS ( REAL EASY). The price is RIGHT, service GREAT, and quality of custom bracket is EXCELLENT !!! YES, we are VERY pleased with them!!!!!!
