Need advice..very pissed

The shop is slow so i pulled my 318 out and started working on it...installed oil pan and timing cover..proceeded to install my summit sfi damper...well everything was going smooth untill the damper stated hiting the timing marks built into the cover:mumum:....i looked at the summit sight for anther timing cover and the all have the marks built in....

the balancer is for a 273-360..i have anther timing cover off a 273 but its pretty pitted..that one has the timing plate...but i can see how it goes on...what should i do............:mumum:
