I found a post with a list of parts in the archives with part numbers for the rear exhaust to trans mount bracket "kit" as per Volvo tech bulletin #25709 for pre 92' 700 & 900's and bought all the parts. They arrived today via UPS. The list was as follows:

#3507501-9 - Tail support for transmission
#6842241-9 - Bracket (from trans. to exhaust)
#9135511-1 -Clamp for B230F OR
#1346590-1 -Clamp for B230FT
#946472-8 -4 screws for tail support (longer than what are now there)
#946173-2 -1 screw for exhaust clamp

After careful scrutinizing, the only parts I can actually use seem to #6842241-9 (the actual bracket) and #946173-2 (the bolt that would hold the the exhaust clamp to the bracket). #3507501-9 is the tail support that is identical to the one my car! #1346590-1 clamp for turbo downpipe is the one that goes to the bellhousing bolt and has an angled flange that doesn't match the angle of the exhaust bracket (horizontal) and therefore will not work unless I bend the bracket. And #946472-8, the longer bolts are not necessary since the bracket thickness is only .087 of an inch! The parts (2)I can use only cost $15.67. Add to this about $4.00 for the correct clamp, for a rough total of about $20. I have read in the archives that the "kit" is around $50.00. The rest the parts I may not be able to return since the were special order.

    Exhaust Vibration Bracket up for grabs

    You may want to check that the 1/4" wire spring that attaches the downpipe to the engine block is actually bolted down correctly. There should be 3 screws and 3 flange washers, two of them bolt down to the downpipe and one bolts down to an "adapter" that somehow attaches to the engine block. That's how it is on my '93 940 NA at least.

    I have replaced my exhaust vibration bracket without first checking that downpipe holding spring (bracket). The screw that held it to the engine was missing :)

    Another issue: non-Volvo downpipes (I had to replace mine some months after doing the bracket job) don't have the flange into which to bolt that vibration bracket anyway, so maybe that's what the extra parts you have were for.

    Anyway, I have got my new rear tranny mount and I will be thus parting with my now-useless bracket when I replace the mount. If anyone wants the bracket (it's 6 months old) it's up for grabs. I'll ship via USPS to anyone who will cover the postage. If somebody getting it will also want adding some bucks for a beer, my PayPal won't mind either :) The tips are optional, of course ;]

    Cheers, Kuba

    When you install this, make sure you check for access to ALL the pan bolts after it goes in. The genius who engineered my bracket made it so that it obscured two bolts. I had to remove it and grind it down enough so that I could remove the pan in the future without also removing the bracket. Better to modify it before it goes in.
