I know Leigh.  It's very odd.

I've been searching everywhere for the answer.  Two suppliers gave me the option of 2.75" or 2.81".

I found this on the net...........

No info on the offset though.

Didn't think upgrading brakes would be so difficult.

One thing is for sure, companies sell their brake upgrade kits noting it's for a specific model, but when you want to buy it they ask you to double check the measurements.

Why promote a part for a vehicle if they don't know if it's going to fit.  And to top it off they know nothing about the vehicle they are selling parts for.

You would think they have a listing of the offsets if they are going to ask the question.

The first company that can confidently provide me with info on a brake upgrade install on my car will get the sale.

I'm fed up with it now.

Rebuild your drums using quality parts, they'll work fine.

I will buy shoes and cylinders for the original drum setup and see how we go.

Do you think after 38 years the internal components like the springs will need replacing?

I've put 212,000 miles on my barge in the last 13 years.  The only thing I've replaced are the self adjusters and (of course) a few sets of brake shoes and they work well.  Having said that, all the stuff is available to rebuild them 'like new', so it wouldn't hurt.

I'm only speaking from my experience, but I think the biggest problem drum brakes have in our sort of car is lack of use.  There's a lot of moving parts in drum brakes and they need to be moved regularly.

I may as well spend the little extra and make it like new.

You certainly put a lot of mileage on your ride.

I need to get out and about a bit more.

After it gets the paint job refreshed in April I'll be happier to show it off.

Bit embarrassed with the way the paint has bubbled on her.

I've had other american cars that I've put more mileage on in less time.  When all these cars were new, they were built for use (and used as) as daily transport. 

As far as being embarrassed about the paint showing it's age, don't worry about it.  What others think about your car isn't important, as long as you like it.  The paint is lifting off my car in plenty of places, but that's just what happens as they get older.  Far more important for me is that I can jump in that car and drive it to Adelaide and back with confidence that it will perform flawlessly.

The Transam starts first time every time which is a bonus.

Guess I just need to look at the bright side.  Glass half full eh. :)

Exactly.  You own a '77 Trans Am.  How many other people do you know have one?

Not many. As long as I have money in the bank account I will keep it.

Puts a smile on so many people's faces which is what makes it worthwhile for me.

Probably the same reason why everyone in the club has one.

And I'll never get sick of that v8 sound.........
