mornin

Also how hard is it to come by the pieces the headlights mount in the aluminum or what ever the guy put square superliner lights on it and I would like to put the factory round ones back in it 

Thanks for the replys any help on putting a sleeper on a day cab? How well do the Mack air rides ride haven't really drove many Mack trucks

I am new to Mack. Been more of a Pete guy but have found a lot of really cheap old Mack trucks Ihave been thinking about buying this one 79 r model. It has an air shift 12 speed with a 300plus motor. I want it more or less for a farm truck for now and I'd like to stretch it and put a sleeper and air ride on it just want to knowa few things this truck doesn't have an engine brake I've done some reading on smacks thermodine and some say it's a joke others like it and I know Jacobs makes one also is it true you need a different cam with a thermodine I assume this isn't a air ride cab do they make a kit to make it air ride. Who is a good supplier of parts as far and interior goes on theses trucks anything  I should look out for truck pulled low boy and has a two like wet kit 

Thanks
