thank you guys!! ;D
here is a small update again...
wheel mounts
engine mount
front suspension-dampers and springs
brake discs and calipers
everything into their places
gearbox
clutch fixed at the rear of engine
engine and gearbox joined
driveshaft had to be fixed permanently as well, as nothing is intended to rotate
powertrain inserted into chassis, the process didn't require any glue as the parts fitted tightly enough
marriage was not perfect, as a small gap has been left between engine and its mount
shaft's other end came out satisfactorily
thanks for watching! next up the rear end....cheers
