Hi guys

hears my situation.. my daily driver a 998 with a remote box neds a new box i have 2 rod boxes will they fit?

are the remote and rod boxes swappable ie will a any rod box fit on any 1275 block? i know ill have to change everything from the diff back that's no prob.. just wondering about the detentions box to block?

It'll fit on the block, but there's a lot you'll have to swap out. I'm not sure if the transfer gears work no problem...

Essentially the rod boxes (DAM2886 or 5626) will fit both small bore and large bore blocks of any age. The shape of the block flanges are slightly different between early/late, small/large bore, but the bolt/dowel holes are in the same place. Just use the correct gasket - the proper kits have three strips to cover both options, just pick the correct two.

You will need the matching A Plus transfer housing and A Plus drop gears because the bearing size for the idler gear is larger in the later gearboxes (A Plus idler has a larger shaft diameter). Technically you should allways use the matching transfer housing anyway (to make sure the two bearings for the idler gear are dead in line with each other) but if you want to use an earlier transfer housing and A drop gears, MiniSpares (and maybe others) do sell a sleeved down bearing assembly you can install in a later casing to make it accept early drop gears.

The only other issue is the tunnel in the car - the rodchange assembly mounts differently and the later tunnels were larger (and square) so you may have clearance issues with rods and exhaust on the earlier round tunnel.

Schrödinger's cat - so which one am I ???

i prefer a rod change box, can be done as Rod says, but its a little bit involved...

there is a conversion bracket for the linkage thats advertised on the mini mania site for converting between remote and rod, i made my own but it gets tight in there with the exhaust especially if you are running anything large bore

its probably easier if you just buy another box in good condition?

ok guys ive decided to take the case clean it up and build a new rod box ill be buying parts after xmas just hope the box i have holds in till then

also the fins on the box is it possible to cut/grind them off smooth yess they help cool the oil and all that but could i just run an oil cooler to make up? i guess the other thing is strength how much would it weaken the box if i remove the fins?

i wanna grind/sand/polish all the aluminum casings to look show room
