I have a complete weber conversion kit if anyone is interested, they are
32/36 dgev carbs with all linkage/gaskets etc., I pulled them off a parts car about 5 years or so ago, they were used less than 1000 miles. I believe the weber part # is K245. They are design to fit 65-72 220SB, 230, 230S, 250, 250S 6 CYL equipped with dual Zenith 35/40 INAT carburetors. Production date of the carbs is 07/99, Current list is around $1100, discounted you can find the kit for $850, I am looking to get around $400, thanks, tk
