I wouldn't have thought it would make any difference - although the length could affect its throw ...
It won't be to do with the position on the splines - that would just change where you were centred.
If the throw is different then just adjusting your lockstops should sort it out.
I've had two with disco arms and not noticed any difference.
If they are the same dimensions as Gwyn's they are plus 2" in compression - if you got a +5" you will get +2 upward travel and +3" of rebound or droop.
So unless you want to go the dislocation route just get +2" shocks.
Old one out - made a start on the one on the car, tried leaving the drum on - but. It clearly needs to come off. Rain has stopped play for today though. I'll see if I can get some time on it tomorrow.
I've just fitted a RR LT230 to my Td5 and the transducer won't fit the drive - the plastic drive is a little too big.
Reading around everyone seems to say they just plug in - though I've found one thread with someone saying the same happened to them. No resolution listed for it though.
Any suggestions? Do I file down the plastic drive (carefully) or can I pop the drive out and replace it?
My blue one started just like that - and deteriorated to not starting at all. It was the solenoid - I bought a repair kit off eBay and fitted it in situ from under the truck.
The copper contacts had eroded.
