Advice on ‘74 Duster

well...I didn't do my homework well enough and got taken by the high of the buy. I am man enough to admit i screwed up and made an expensive mistake.
Go ahead, tell me "I told you so!" :mob:
Needless to say I feel really dumb:(
Dont get me wrong I like the car but haven't been able to even enjoy the car as it needs all these repairs. On the bright side The car is solid underneath. no rust.

My car is in the shop now getting the 904 trans rebuilt, it needs a new timing chain, motor mounts are both broken, radiator started leaking in multiple places and needs replaced and the msd box wasn't even working as it was hooked up backwards! Its fried now.
The distributor wasn't even the correct distributor for the car. Oh and just found out the gas tank is leaking too! I am replacing the carb also as it only has a 600 cfm carb and just seems way too small for this 360 so-getting a 750cfm edlebrock.

The headers are hitting more than the steering column as I first thought, they are touching everything underneath the car and are a generic header not even made for my car! Someone just stuffed them in there...:wtf:

Can anyone suggest any headers for my car? My friend says i should get shortie headers to get proper clearance.
:thankyou:
