REPAIR DETAILS

I am having trouble putting 2 things together on the car. I can share photos if anyone is serious about helping me. I have most of the parts to relocate the battery to the trunk and I have all the parts to a set of coilovers that connect to an air piston lift system and would like to install that and remove the existing parts. The car is on a flat concrete surface, I can put it on stands if needed, wiring would need to go through the interior of the car to the trunk, the interior is already removed and there is no hood on the car. I can pay for good work and help
