What I have is a 1969 Mach1 with a 445 stroker with a Big in and out wide ratio with a 3.89 locker gear and a 28 inch. tall tire. I am wanting to start to drive the car on more road trips then I use to. I am looking for thoughts on what would be the best for a overdrive. As of now my 4 speed shifts fine at 6200 rpm. I seen reports on the TKO not shifting at that rpm, even with the updated work to the blocking rings. True or False? I do know what is all involved with installing the TKO and the gear vender. One question about the GV, will the factory parking brake cable and hardware still work as before like it did with the top loader. Any input or thoughts would be great. Thanks
