installed the ram air and the tuffy box. pleased with the results but had a little bit of a struggle installing both. the ram air on my 84 didn't really leave alot of room to install the hose from the firewall. it had to squeeze past the emission pipes and the a/c hoses . the center console with the cupholders in the front would not catch flat metal had to drill two new hole in the console to make an easier and secure fit. besides all that it went well and am pleased with the results.
