Will this work in my Flat Four banjo?
It says it's 3.25" diameter

Banjo horn button is 3 3/16" which equals 3.1875 so it might be too big for dropping in.
There's another discussion going on horns and there might be some information that will apply:

fpcopo. I just posted some thoughts under the above thread if you are interested.
-Stoddard reference P horn button to be 82mm.
-banjo/flat 4 reference 81mm for their buttons.
-sierra Madre references their P car crest buttons to be 79mm
... Go figure!
... I have seen several original P cars with the flat four golden lady and st christopher horn buttons installed.
cheers
Frank...If the Sierra Madre one looks like it will fit, give me your exact measurements with a caliper (Thousandths) and I might be able to go over there and measure theirs if it's in stock. It's only 2 miles from my home.........Bruce
Going out of town for a week. Will get with you when I get back. Thanks, Bruce.
Here's what I did:
I've put in a flat-4 horn button (which will fit a Flat-4 Banjo perfectly... Obviously) and then I took a piece of double face foam tape and glued a C horn cap on it.
Works perfectly:
More pics of the Black Betty, please. That car is the juice.
What is a c horn cap and where do you get one?
niiiiice black betty!
you build it? (i don't remember seeing a build thread for this beast)
what muffler you running? that's an A1 sidewinder, eh? I have a 2056cc T4 with a sidewinder and magnaflow. i've never heard mine (as a passerby), but your sounds AWESOME!
Well... A C horn cap is a horn cap that was used on the steering wheel of a Porsche 356C 
I stil had one of these lying around (an original one), so I just glued it on my flat 4 horn button...
I see now that those caps are quite rare:

It's just a horn cap that is used on a Porsche 356C.
I hate to hijack this thread...
I did it all myself; I even helped making the (special) body. This body was made by a friend of mine: Gé Vaandrager. He is a magician with GRP and moulded a real Speedster. From this mould he made 10 Speedster bodies and mine is the last one he made (#10). This last body was converted and modified to my specifications.
The exhaust is custom made by EPS (Exhaust Power Supply); a Dutch company that makes unbelievable nice and great SS exhausts: www.uitlaten.com
This is the build thread on the Dutch Porsche forum: http://www.porscheforum.nl/vie...php?f=17&t=14685
holy **** - your attention to detail is superb!!

Goede Middag and Halo to another Dutchman! Just saw your thread and will check out the Carrera you built tonight at home (can't get onto Youtube at work 
).
