These two steel adapter bolts on all dual weber intake manifolds. At 30mm height it is an exact replacement for Rubber isolators with the original rubber 45mm mounts out of production. This is a very good modification that unlike the old rubber mounts will never need replacement.

• Use Weber softmounts on carburetor side
• At 30mm height these are 6.5mm taller than the stock rubber mounts.
• With the 6mm thick soft mounts, this adapter extends the lenght of the intake renner by .500" (12.5mm). This extra lenght is reputed to make more low end torque.
• 40mm inlet manifolds must be "Bell mouthed" to match the 45mm ID of this mount. With 40mm webers this is no problem. Actually, the 2.5mm step created behind the carbs create an auto reversion barrier and cancels negative pressure waves (mixture stand off).
