JX ex. turbo to downpipe - bolts or studs?

Evening all
Replacing my early jx exhaust, the old one was fitted to the turbo with bolts. As a precaution in case something broke, and before checking how my exhaust was fitted, I had bought studs (http://www.brickwerks.co.uk/index.php/t ... studs.html" onclick="window.open(this.href);return false;) and copper nuts. The bolts I removed seem pretty corrosion free, are 20 and 25mm long on the threaded portion, and are variously marked FS A2-70, THE A2-70, and ABP A4-70.

Should i use the new studs and nuts, or the old bolts?

And if I use studs, how best to make sure they are all the way home in the holes on the Turbo?

Many thanks

Roger

Normally to fit studs you would lock two nuts together on the stud (two spanners) and then use the top nut to wind the stud fully home before removing the nuts. I would prefer studs and nuts on an exhaust, unless clearance issues mean that the exhaust can't be taken off the studs, but I don't know if there are particular reasons on the JX to prefer one over the other.

Would that also be known as an 'Allen key' per chance??

Nuts it will be then, in the absence of a stud inserter.

Cheers, m'dears.
