first of all parts are still available and not that expensive ..got 2 in workshop..1 with d15 n other with d17 ...
what u have done is not unique work.. upgrade to 96 civic to 2000 makes sense ..... but i dont know what u did this
and 96 and 2000 parts r expensive then 1990 civic
if u had to make the rear end like this ..you could have done the US model civic rear end ..still round shape n box shape will never look fine together
rest its yr money and your choice .....
