Hey dude. Have you heard of cutting and welding the front half of the coupe/hatch fender to the rear half of the sedan fender? It is apparently the most effective way of achieving this conversion, professional help is recommended as it is quite technical but results are nothing short of PURFECT. You are going to need a set of hatch fenders and a set of sedan fenders as well. Coupe bumper, coupe/hatch corner lights (to fit the front half of the coupe/hatch fenders) and you can use a sedan hood. Radiator support stays the same. The weld is right at the top of the arch of the fender.
I have talked to
floored4door and
93civicsedan from Honda-Tech who have completed this:
floored4door
93civicsedan before (with just coupe/hatch bumper)
93civicsedan after (with modified fenders, hatch bumper and coupe/hatch corner lights)
There are numerous ways of completing this conversion, but I have found this is the cleanest and most OEM looking method. Using modified hatch/sedan fenders, the fender and bumper lines are smooth and even along the wheel arch (notice floored4door) which is impossible to achieve by just using the hatch bumper alone because the hatch bumper lines are much thicker than the sedan fender lines. Also if you notice the 93civicsedan before shot, the sedan corner lights on the drivers side do not sit even and protrude from the hatch bumper as opposed to the after shot. IMHO if you're going to do it, do it right, This conversion looks AWESOME done properly and usually people only hate when it's not done right.
GL with it bro, hope this helps
