trying to figure out how much different a delsol rhd swap is from a eg civic rhd. beside dash. please help thanks

 

The shifter for the Del Sol is a different length than for a Civic.
From this I infer the engines are probably different distances from the firewall.
Check this carefully, if I'm right it could be a real problem deciding how much sheet metal you change.

 

the thing is you don't change shifter area tho only the firewall
