Hi guys, I bought my big one a new engine oil tank. Unfortunately replica from Taiwan as it turned out afterwards. Problem: First of all to get out the old orange original oil tank. No place, came with the petrol pipes as well as the exhaust under it not to pull them out. Axle, starter as well as exhaust screwed down. New oil tank used however, we now stood in the assembly of the exhaust now at the new oil tank. That seems to have a flatter curvature or It’s a little deeper. Maybe 0.5 cm. Both oil pans look the same with the eye. Well, now we had to separate the exhaust with the Flex and just improvised and welded three exhaust pieces together to somehow get past the oil pan and to the fastening cuff. Some solution because that can’t stay. Is there a exhaust piece from the aggregate carrier to the trouser tube that is different or deeper? Original version would be great. Exhaust system is 2.5 Z oll Dual Exhaust without cat. 1984 Trans Am. picture in annex MfG
