First, which weber is it? You can go to <a href="www.carbs.net" target="_blank">Carbs.net</a> or <a href="www.redlineweber.com" target="_blank">RedlineWeber</a> to ID it. It could be a 32/36 DFV, 32/36 DGV, or 38 dgas. BTW there will be one vaccume hose hooked to the Weber and that will be the Vacc advance to the carb, all the rest are obsolete, including the ECU under the blower motor under the passenger dash. <img src="/forums/images/graemlins/notooth.gif" alt="" />
You will need the Redline adapter plate to mount the Weber to the mitsu intake. You will also need the throttle cable bracket to move it over on the valve cover.
