Cheers funkyhead, think I'll press on then :thumbs:
Word of warning...make sure you give the studs/bolts etc a good spray with wd40 or something, I didn't at first and snapped one of the 5 studs clean off, problem is they are fixed/welded in so it would mean taking the manifold off and trying to weld a new one on or replace the manifold as well.
Also the 2 bolts connecting to the back cat were in bad condition and needed heating up and a socket hammering on before they could be removed...I started it on my drive way and ended up getting it finished at the garage...oh and big garages won't touch a 2nd hand part...what trouble I had, luckily I found a smaller garage who swapped it all over for £30.
I'll be interested to know how you get on with it mate. Hope it all goes well!
