There was this service letter: M-1963-1, dated Feb 11, 1963. the forum will not let me post image. will keep trying.

I believe New York was the other.

400+ cu in engine? I thought the largest Packard production engine was 374 cu in.

The lower door hinges on later Stude Avantis as well as later Avantis have slots on both the frame and door side.

Interesting. This is what I see on my phone. Ebay must have different displays for mobile devices.

I did not see a service bulletin. The revised part would also work on earlier cars. The upper hinges did not change. Checked a lower hinge on a 78 and it also has elongated holes. My guess is that Studebaker decided they needed a bit more adjustment for the doors to fit correctly. FWIW, I made a post a while back about a change to the rear quarter interior panels from 3 pieces to 2 pieces. Not listed in service bulletin or parts catalog.

Working on R5423. Noticed that the lower door hinges are longer and have elongated bolt holes. Checked R5408, and they are the same as R5423. Have one from R4551 that I am rebuilding pin on. First picture is from R4551. Second is from R5423.

Spoke too soon. Just noticed Kuwait license plate.

Odd that the ebay listing does not state anything about the car being in Kuwait.

IMHO, the best thing to do is have a local clutch rebuilder redo the pressure plate and clutch disk. Much better results that way. Throwout bearing can be sourced from one of the many vendors.

R3 motor mounts were also shorter.

is this the one in question: https://www.ebay.com/itm/267120563514?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=1A_eGthAQya&sssrc=4429486&ssuid=8XIBhyveTMe&var=&widget_ver=artemis&media=COPY

According to Wikipedia, 588 Packard Hawks were sold.

IIRC, when I c.c.'d a pair of 1557570 heads 58 c.c.'s seem correct. I am not sure where the 54 c.c. figure comes from.

Several auto manufacturers cooperate on their offerings without merging. Think Mazda and Ford, Mitsubishi and Chrysler ...

I think Fiat and Chrysler merged. The merger with Renault failed to go through.

FWIW, Nash and Hudson merged to form American Motors. Nash Rambler was a model. Kaiser Jeep was purchased by AMC much later, maybe 1970 or so. AMC was purchased by Chrysler around 1987, mostly for the Jeep brand. I read somewhere that Studebaker was discussed to be part of the merger, but that obviously did not work out.

Both of my 64s came with the quiet exhaust system. Both have mufflers and resonators. The exhaust system with mufflers, resonators, and crossover are available from Park's Pipes.

Likely stretched cable. There is adjustment just behind the x member.

I tried both walnut shells and soda. The old undercoat was too soft. Both kinds of media just bounced off.

The 3M 544 dries harder than I expected. Was hoping for something similar to the old asphalt base. Thought about just coating the fenders and rear wheel wells. However, all four of the Stude Avantis I own have full undercoating. Some PO may have applied the undercoat as all have been repainted at some point. I will say the hardest part of the job was removing the old asphalt undercoat. Lots of scraping, heat gun and mineral spirits. Here is pic before new undercoat. Was a little sloppy with the black paint on the metal bits since I had already decided to coat the entire bottom.

I have just finished undercoating one of the 64s. Used 3M rubberized #544. Took about 3 gallons using a cheap tcp global undercoat gun.
