    well I picked up a pretty nice 88' shaker classic severe duty sba truck with a 300" wheelbase and a 80" double eagle sleeper with airride on it. the truck has a 3406b model cat 425hp in it was inframed about 200k ago, gotta find out which one, has a smaller turbo on it. with a 15spd eaton remaned, eaton 3.70 40k rears with airliner airride. truck is really tight and solid I like the fact it has a full size bed in sleeper but besides that the wheelbase is what I really like.

    anyways on to my ideas I want to convert this thing to a SET FORWARD AXLE now to those who might be able to help me out with this please shine your insight, I really don't need any negative comments about it I know it steers better the way it is now, I know its a lot of work (in Miami you can make anything happen) and I know the wheelbase will be even longer so please keep the negatives to a minimal I understand constructive criticism but lets not be ##### please.


    well other then needing the SFA short hood I know I will need to change bumper as well.
    front axle needs to be moved forward im figuring im going to need measurements off a truck to see were holes need to be drilled (would be great if someone here could give me some lol)
    also steering gear box gets moved forward so im guessing the steering shaft needs to be lengthened comparing it to my old flc, and the pressure and return lines coming off box will need to be lengthened as well.
    Front brake air chamber hoses will need to be moved forward and a hole drilled for bulkhead fitting to go thru chassis.

    my big question is the OILPAN i had looked at a old what i was to belive a bmodel cat oil pan and it looks completely symmetrical front to back side to side meaning can i get the same front sump oil pan that's on it now and just flip it around??? or is there a difference? other then the fact i know i will need more then likely a oil pump pikup tube for a rear sump motor rather then a a front sump what else is different if anything?

    i know engine,radiator,air cleaner all stay in the same location so theres no issue there with them. the lower part of the cowl is a little different being that it has a lower flare that's riveted to the cab cowl which i can de rerivet and custom make a lower cowl panel to match lower rear part of SFA hood. as well as the hood hold downs would need to be remounted further up then down low as the SFA hood has them but that's no issue.

    well any insight or thoughts on this idea would be great, i know i can find the older flc hoods that i want for not a bad price, and the front bumper is what i really wanted to change anyways so this would know out two birds with one stone. the old SBA hood and bumper i can sell to one of my buddys locally who have a banged up set on his this way i can recoupe some funds lost on coversion. piglet.png

    No personal experience , but I once saw an F/L COE that was rebuilt and mounted on an FLD chassis. The front spring hanger assemblies were apparently interchangeable and even had the same bolt patterns.

    So I think that this could be a straight forward conversion. But finding the parts might be a bit of a challenge. There aren't that many FLCs left.

    that's true but i don't only need to use a FLC hood specific i can use the newer classic short hood they are both the same length.

    There may be an issue with the height of the radiator/ coolant tank. The FLC hood is much taller than the Classic hood. Also, is yours air or water after cooled ? That may not be an issue. But I'd think it would affect the distance in front of the radiator.

    Also, after about 2001, Classics were redesigned and mounted on a chassis shared with the Columbia/ Century. Something to keep in mind.

    Unfortunately the oil pans are different. The front sump pans don't have clearance for the oil pump drive gear molded into them on the shallow end that the rear sump pans do. I never understood why Cat went to the trouble to make different pans when they could have used the rear sump pans for both configurations.

    You will probably have to relocate the dipstick tube to the rear as well.

    thanks guys i was fearing that with oil pan, so im goin to need a pan and pickup tube huh?
    i have alead on a hood in alabama just need someone to bring it down to florida for me.

    as faras radiator and tanks they are pretty much the same radiator in dimensions both have tanks up top but instead of having the radiator tanks on the sides it has it on the top and bottom.

    i wonder how hard it would be to get that pan
