Hey Chuck! Glad to find you here , you are a man of taste! yes the new glass aeras and the bolo turret are injected parts. The fit is pretty good and the resin is top class. there are some minor shortcomings to acheive a true A4, but nothing insurmontable.
keep in mind that you need Eduard's masks (a must), seat belts and wheels beside the resin set, a fact to consider for your budget.
best regards to Manhathan beach for me!
