pmolitor Posted November 25, 2011 Share Posted November 25, 2011 Just wondering if a 1990 superliner cab will work on my 1979 rs686? I found a nice cab and know i'll have to change the driver side cowl. Hoping that's the only mod to be done. Quote Link to comment Share on other sites More sharing options...
Underdog Posted November 25, 2011 Share Posted November 25, 2011 Just wondering if a 1990 superliner cab will work on my 1979 rs686? I found a nice cab and know i'll have to change the driver side cowl. Hoping that's the only mod to be done.Superliner cab, especially late model Superliner II is quite different than a standard R cab. Much easier to go out and find a similar donor than to make all the changes required.Gregg Quote Link to comment Share on other sites More sharing options...
Superdog Posted November 25, 2011 Share Posted November 25, 2011 Did you try Vander Haag's?You might also call Housby in Des Moines,ask for Drew. Quote Link to comment Share on other sites More sharing options...
pmolitor Posted November 25, 2011 Author Share Posted November 25, 2011 Drew has a brand new one but it is more than I can spend. Plus all the little parts to make it work would make it really expensive. I found the superliner cab complete for $900 so I was hoping it would work. It's in the St Louis Craigslist.

MACKTRUCKS4 Posted November 26, 2011 Share Posted November 26, 2011 You will have to change the right side also because the superliner in not indented for the air cleaner.

terry Posted November 27, 2011 Share Posted November 27, 2011 Manders just outside of Minneapolis used to have a ton of mack cabs. terry Quote Link to comment Share on other sites More sharing options...
Rob Posted November 27, 2011 Share Posted November 27, 2011 I have repaired many of both types of cabs. From a retail standpoint you would be much better off to find the cab you need rather than convert although I'd love to do the work for you; $$$$$ JK.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

pmolitor Posted November 27, 2011 Author Share Posted November 27, 2011 How much would it cost? That superliner gives me some nice upgrades. I'd gain air ride, electric wipers, new style door latches, AC, and good interior panels. I'd really like to find a complete donor truck with a complete AC and 8 or more speed Mack transmission. I have a A 6 speed right now and can run 72@ 2300 rpm. I'd like to get down to 1900 rpm. Quote Link to comment Share on other sites More sharing options...

It is not a small job compounded by both sides. I really think you can find a decent cab for less than the cost of conversion, or possibly a complete truck. You are asking about something quite late model and since these cabs were prone to rust, the cost for a good serviceable cab is quite high.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Superdog Posted November 27, 2011 Share Posted November 27, 2011 Manders is showing a 1990 RS688 cab & chassis,stock # 4728 for $4500.Looks to be an ex-mixer truck.Cab & hood look nice in the pics.You could swap cabs and resale the rest and come out pretty cheap.

pmolitor Posted November 27, 2011 Author Share Posted November 27, 2011 Housby has a brand new never been on a truck complete with windows and doors for $4500. Problem is after all the extras and swapping I.swapping interiors, wiring and air it will be a lot more than that. Quote Link to comment Share on other sites More sharing options...

Lmackattack Posted November 28, 2011 Share Posted November 28, 2011 I think you would just be creating a nightmare if you bought a r cab and converted it to a superliner. Just the bodywork involved would be a pain. You will find that the R model cabs had slight changes over their years. Some things that I noticed were diffrent door latches, exhaust mounts on the cab,wireing, cab lights/horn placement. Air cleaner location. Air ride cab, hood rest on the cowl. Radiator mount...there at some of the things I had to deal with when upgrading my 1977 to a more modern cab..Trent Quote Link to comment Share on other sites More sharing options...

But there must be a jillion spot welds holding the thing together that must be drilled out individually. It's a lot different and faster when you are not trying to save the old panel(s). This is what drives the cost so high for this type of modification.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

pmolitor Posted November 28, 2011 Author Share Posted November 28, 2011 I've changed the exhaust to the new bracket s which will let me run newer air ride if I want. I have a western so I have to keep my hood and raise the air ride mounts 3 in. I rebuilt this entire truck 7 years ago which is how I know the cab is shot. It has so much putty and welding done to it I don't even know where to start over. Quote Link to comment Share on other sites More sharing options...

David Posted November 28, 2011 Share Posted November 28, 2011 I have a two stick.That's a direct. A mack 8sp is way too fast. A 9sp will work but you'll loose the lo hole and will need a new pto. Quote Link to comment Share on other sites More sharing options...
