hi there i just signed up

i just wanted to know what is the best way to fit this also i would like to fit a delta extension on top of that.

any help would be great

2most common ways:
have it bolted on and bodyfiller, sand and paint the holes,
or just go for the old tigerseal and glue it on, aslong as you do it right it wont come off
