Hi Guys, Hope you can help a newbie
My exhaust is fubar , so I'm looking to change the intermediate section and back box. Here's the question ?
What size are the three bolts that make the seal between the Intermediate section and front pipe ? the best guess I can come up with are 1/4" x 1 " ??? UNF or BSF ???
Series 3 88" Diesel 1972 (3 bolt exhaust)

Cheers

What spanner size are they. If they are 1/4" thread size, imperial spanner will be to big for 1/4" UNF. 1/4" UNF (7/16" spanner) will be to small for 1/4 BSF.

When I ordered these from Craddock's last time they forgot to include them so I had to just use whatever I had available, that was three years ago and they're doing OK, will need a new exhaust next spring.

I've tried searching for part numbers, but no joy for Craddocks or Paddocks. Even had a look at dingo croft :-(

if it's just a nut and bolt, use anything that fits - the thread size is immaterial.

Just grind the old ones off and fit some shiny new metric ones
