Been searching and have had no luck. Does any one know the proper bolt sizes for an A+ engine

- the small bolts on the front subframe upper arm? Two per side
- the bolt 3 bolts that go into the clutch cover for the engine mount?
- the two bolts for the heater tap off the cylinder head?

Thank you for any help.

Front sub-frame upper arm retaining plate bolts are 1/4" UNF.
Engine mounting bolts into clutch cover are 5/16" UNC.
Heater tap bolts (or studs) are 1/4" UNC into the head. If studs they have 1/4" UNF threads and nuts on the other end.

If you need new bolts, just establish the lengths anbd you can order them from Namrick Ltd on-line (Google them). They also do a 450-piece UNF selection for about £17-50 which is excellent value if you have a Mini. You can buy the UNC sizes separately as you don't need many of those.
