More 72 LT1 ?'s - Sorry

[Joe S.]

According to the JG all LT1's had a bracket between the carb and fuel inlet tube. Mine is missing which makes sense as the original carb was in a box and a replacement 780 was on the engine. I've checked all the obvious vendor catalogs and have not seen this bracket. Suggestions on where to obtain one? Obviously a swap meet or Carlisle but I'm looking to complete this sooner than later. This is really all I am down to finding while doing the bodywork and paint.

Same goes for the Waterpump/A.I.R. Pulley. I do not see them available anywhere. I have a complete A.I.R. system (ala Bill Hodel) and need the pulley.

Coil (B-R 270), Capacitor, and Starter (1108418) Ditto.

Does anyone make a decent repro rocker panel? One is already a replacement (no tab) in decent but not show condition and the other is an original but driver quality.

Now for a real dumb question. I see one horn mounted between the headlights right in front of the hood/center. The horn always sounded terrible like one horn was all that was there. That may be the case because I can't find the second one. I went through the AIM but couldn't find it in there either. Only the front mounted one. Where does/did it mount and where to get?

Thanks!

1) The 70-72 LT-1 fuel line bracket is available in reproduction. About 20 bucks from Paragon or any of their dealers like Dr. Rebuild, etc;

2) The original AIR pump DRIVE pulley, GM #3991425, is not, as far as I know, reproduced. A 100% functional, if not absolutely correctly configured replacement, was, until recently, available from GM under GM #14023158. It is no longer, though. Both of these pullies are unique to Corvettes and a few MD and HD truck applications. So, they are not "everywhere to be found";

3) No one currently makes a rocker panel reproduction that it identical to the PRODUCTION rocker panel;

4) 72 Corvettes were originally equipped with a single horn. You could add a second horn, but it would not be original. The choice is yours, though.

U da man Joe, thanks.

I went through Paragon's and the Doc's catalog tonight. Maybe too starry eyed but did not find the carb bracket. Will check again after a lttle snooze.

They do list the pulley but it says to Call so wll try there for the pulley.

The rockers are another story.

As always, thanks

Most likely, if they have the pulley, at all, it will be the 14023158. Now that it's been discontinued, that will likely increase significantly in price.

Addendum--Photo

Attached is a photo of an NOS example of each pulley I mentioned. There is a very subtle difference between them. However, the part number is stamped in a location where it can be easily seen.

Last year of dual horns was 1970 model year.

Joe, I have what I thought was an original smog pump pulley: it has the 3991425 followed by BX. What's up with the BX? Thanks, G.

"BX" is the "broadcast code" for the 3991425 pulley. Most GM pullies were coded with a 2 or 3 alpha character code. It was easier for assembly workers to ID a part from a 2 or 3 letter code than a 7 or 8 digit number. The 3991425 pulley was first used for the 1971 model year and for quite a few years thereafter (for AIR-equipped cars).

Thanks Joe *NM*

Thanks John. I looked through the entire catalog (v30/2005) and especially pages 43-45 with carb/fuel items. Still couldn't find it.
