Welcome to the bb; good luck on the restoration.Hi Andrew,
Welcome to AlfaBB. You'll find a lot of helpful information by searching and posting to the 1900, 2000 & 2600 (1950-1968) forum and the Yahoo 2000/2600 newsgroup. With respect to the weatherseals, check with Re-Originals Down Under. As far as I know, the seals for the front quarter windows are not available because there were never enough owners coming together to have a sufficient number made to bring the cost down. Please post some pictures of your car so we can see how good or bad it is.
