1988 Fiero Formula T-Top Red 5 Speed. I cannot seem to find replacement front exhaust manifold replacement for stock unit. I see the rear at the Fiero Store. What am I missing?
How can I get a replacement and what parts do I need to order for a local shop to be able to do the replacement in one day? It's my work car, believe it or not. Thank's in advance to all the kind kindred.

Keep in mind that is is likely that the shop will break off at least one of the exhaust studs when they try to take them out. It may be worth your time to try it your self, you might be a little kinder to the bolts than a shop will. Larry [This message has been edited by trotterlg (edited 07-27-2013).]

I have a good used one. It's actually in a set I have, but I could separate them if you can't find one. If you can get the manifold off without breaking any bolts then all you need is a manifold and a new gasket. I need to double check, but I probably have a new gasket too (Fel-Pro).

Tip: Remove the deck lid and loosen the rear cradle bolts about 8-10 turns but do not remove them. Disconnect the dog bone. Jack the rear wheels off the ground and support the car with jack stands. Don't drive the car and soak the exhaust manifold bolt studs and the crossover pipe nuts with PB Blaster for a couple of days before attempting to remove them. If they break off the only way to removal will be by using a special Kent Moore drilling fixture that was designed for the 60* V6 engine. ------------------

I did the front Manifold twice in 2 years when i had my 87. PB buster is your friend as others have said. I sprayed the bolts for about a week once a day. i had to much trouble removing one of the bolts so i removed the driver seat and the back pannel behind the seats and cut a access hole to get at the bolts strait on using a cut off wheel. just be carefull cutting since the fuel lines run behind there. JB welded the pannel back in. also add stud insteas of the bolt with anticease only on the part not in the head. Made my second repair alot easier to do. hope this help you out it was a 2 day job for me figuring out everything and trying all the ideas i seen on here.

I don't recommend cutting an access panel into a structural piece when you can loosen off 2 bolts, and lift the body.
Like Dennis said, unhook your dogbone, and back out the rear cradle bolts until you can lift the body away from the engine. The engine will tilt downward and back and make access to the front bolts do-able. You don't have to remove the deck, but it does make life a little easier.
And I can repeat that PB Blaster for a few days is an absolute necessity.
However, if you can get a couple of carbide bits from a machinist supply place, you can drill out a broken bolt, and then tap it for a Heli-coil.
That worked for me. Good luck with it.

How about $75 shipped for the pair? The front one (closest to the firewall) is nice and even has the stock bolts that attach it to the y-pipe, but the rear (trunk side) manifold has a broken y-pipe bolt still stuck in the welded on nut. I am attaching a picture for you. Both are uncracked and in nice shape....the only issue is that broken bolt. Most people knock it off and reweld a new nut onto it. LMK if you're interested....I can get them shipped out anytime this week.
