Hardtops and interchangeable parts

Morning,

I have a series 1 109 pick up and at present it has no cover for the truck bed. Having dogs I’d rather a hardtop fitted instead of a canvas Hood. Do 109 hard top and sides from a series 2 or 3 fit without modification? If not what about the ifor Williams canopies? Also, as I use it regularly as a work vehicle and until I sort out the rear, do the front loaded pick up roof racks for a 90/88 fit series 1 vehicles?
Any help would be appreciated.

Cheers,
Dalton

Yes they are a straight swap just make sure you get all the fittings, some had a rear door some had a top and bottom tailgate but everything is in the bodywork /roof to have it the way you want it, hope this helps

Ifor williams tops are good but tend to get stollen to order

I thought the series 1 LWB was 107" is the tub longer to the rear of the axle to make the same as 109?
Every days a school day.
Had two 88's and a 86" over the years but never a LWB.
