Just got my first 105 series car to part out. It is a 1967 Giulia Sprint GT Veloce. Been sitting uncovered in the woods of West Virginia for 20+ years so is a total basket case. However, some parts are usuable and in good condition including a uncracked dash, front and rear bumpers (that were inside all this time) and a 1600 engine that turns over smoothly by hand as well as the dual webbers, seats (as cores), 5 BWA wheels (3 caps), etc. Will be posting more pictures as we get the car torn apart in the next few weeks.
BillS (another member here and well known for 105 parts/advice) is the technical side of this project and will be able to answer those types of questions. All parts are located near Hagerstown, MD about 70 miles west of Washington DC.
PS- have a local buyer interested in the complete engine and really don't want to ship it so if interested locally let me know and I will put you on the "wait list".
