I bought a angle grinder for $19.95 and removed the gas strut. The shell is well and truely stipped now.
The engine will be a 4A of some sort. No wild modifications are planned. Just a stock AE86 with bolt ons from e-bay. I want the car to be eligible for a CAMS speed event sometime in the future. (Targa, Improved Production, Drift, Hill climb etc). So forget what engine and little bits for now, I need to get the shell right. I need a CAMS style roll cage. And I am not going to cut the firewall or do anything silly that is not reversable back to stock. (Except the rear seat brackets are gone). And apart from the roll cage, more components will be removed rather than added.
