Recently picked up a 1984 Mustang GLX Convertible. I also picked up some summit racing long tubes and am having clearance issues. On the driver side I've removed the steering column and the headers still are getting caught on the firewall and transmission. Any ideas on how to get them to fit?

What way are you putting them in? Some model headers I have noticed putting in from under car helps. Also I would call Tech support from summit and see what they really sent you.

I tried going from the the top cause it didn't look like it would clear going from bottom

Check to see if your motor mounts are worn. Is this a stick or AOD? Most of the time with LT headers you need to either loosen teh motor mounts, jack up the engine, remvoe the steering shaft etc.

Why do you need LT headers? What is the rest of the setup

It is an AOD, ill try and loosen the motor mounts and jack it up. I wanted a better sound so i went with long tubes and dual exhaust with flowmaster super 10's.

you DO know that the AOD requires different LT headers than an stick to clear the wider trans case I hope.

I did not know that. I'll probably try to loosen the motor mounts and try again. If not I guess I gotta find some new headers. Thanks for the help

my experience tells me that 99% of the time longtube headers are to be installed from the bottom. Jack the car high enough and they should slide right in, that is of course if you have headers designed for your specific application, and yes, longtubes for an automatic are slightly different than those designed for a manual foxbody. The automatic version will fit on a manual car, but not vice versa due to the auto being wider
