Those won't work for you. They're built for the L36 which has even port spacing. The Series 1 L67 and L27 don't have even port spacing.

Your best (only) option is new from GM or from a wrecker.

When I had this problem on my 95, the local wrecker checked the interchangability. The front manifold for my year is identical to an L27 front manifold. (Supposedly) I happened back to the 94 SSEi and since someone disassembled a good chunk of it already I had the manifold in 5 minutes. (Someone had already nicely fixed the cracks on it.

I can check...supposedly I have a manifold being fixed by airplane machinists. They do great work. Don't know if my 95 L67 manifold is the same as yours???

Just talked to my buddy. My pipe is supposedly welded and on it'* way back to me. I've got a spare of something I should never need.

If you are looking for one w/o a heat shield (the new pipe didn't have one) the shipping might be pricey but I'd sell it cheap. Just need to cover what I gave the guy for taking care of me.

I'm glad to hear the 92 L67 rear is the same as a 93 L27. The only difference I've found from the fronts is the 92 L67 has more heatshield.

OK BillBost, PM is on the way. It appears that your FEM is the same as mine. I can either put my heat shield on it (did some nice work on mine, even though butchered the weld), or thinking about sending it to hulkspeed for coating. I am not sure if the thermal coating will be enough protection (with one or two custom TB heat shields) or if I will need to make sure that I put my heat shield back in place. Now to find a REM.

Check with Randman1, he might have a spare REM

OK Guys, I need suggestions.

I found manifolds from a boneyard (they shipped them complete with the stove pipe I needed to fix my little [email protected]#$up) for $78.00 WOOOOOHOOOO I got em, and they are the right manifolds, and cracked in the same place.

Sorry BillBost, but I am not going to need your FEM now (unless I screw these up too).

I am looking to send these out to be welded, cleaned, and thermal coated inside and out.

Any suggestions for a vendor?
