I just talked to Scott at Harm's i have a OE 70 TA Challenger 4-spd six pack setup and OE intake manifold im going to use. Im shipping Scott my carbs for a OE restoration. He said they will work great for a daily fair weather driver as i want to drive it alot good guy to talk to he knows his craft well and i dont mind paying big $$$$ for restored carbs from Harm's. Thanks to all that chimed in i love this site and the members on it Mopar guys really do help each other out .
