Default Need 90 side pipe instructions

A few years ago I got a good deal on a set of used side pipes for my 90 convertible , I have finally found the time to install them and need some help !
Unfortunately they came with no instructions, if someone could e-mail me a set or give me an address where I might obtain a set it would be appreciated !
The collector unit that I believe bolts up to the catalytic won't , unless I cut off the round flange on the catalytic, I think this would work but then it might change the location and the fiber glass covers might not line up , my problem !
I also could use a set of new gaskets .
Stamped on the collector " Lawrence INC. Spring Lake MI. I can't find them online , anyone got an address for this Co. ?

Well they came totally disassembled , I have bolted the muffler's onto the side units and have figuered out where the hangers go everything is lining up in a manner that would make one think it will work if I just cut off the round donut at the back of the cat. just that once we go that route there is no turning back.

Good luck with the install. Getting them centered is the hardest part...but not too difficult. I would recommend you to lightly bolt everything together to ease the centering process.

Wow ! Thanks so much for the link , I will give them a call in the morning,
Got to love this forum , the guys here are the best :party:
I did find some high heat gasket material so I can cut out new gaskets.
I have bolted mostly everything up so I have an idea where to drill holes for the front brackets , still not sure about cutting off the donut on the back of the cat. but see no other alternative , and not sure about the stock rocker panels but I think they must come off :confused:
Hopfully these guys will help fill in the gaps , thanks again :seeya

Rocker panels come off.

There's a whole mess of screws on top and bottom, some in the fenderwells, and one TRICKY one on the backside, just ahead of the rear fender. You'll have the damndest time finding it with your fingers, let alone getting a socket on it.
