Re: Converting a 7 tub into an 8 tub
Well, I have a slightly different perspective.
I guess my answer depends on why you want an 8. I have one and it's great for everything until you get into some really tough terrain (like the hammers). The tail overhang is really a little too long. I've munched mine up pretty good. Now, if you don't plan on running 5+ trails, a scrambler may be the ticket (and then I would agree with the above posts, just buy an 8 tub....they have different lines in the overhang, the wheelwells as mentioned, the supports for the roll bar, etc)
I think the cleanest idea is a stretched 7 to be similar to a bobbed 8. You get the advantages of extra wheelbase, more storage, but no overhang. If you really want to build the ultimate rig, why not just make it exactly ideal for your use? My neighbor has a bobbed 8 and it is Very proportional. He runs 35s, but with 38s you could even stretch the wheelbase a little and it would rock.
If you want to be able to run a scrambler hard top you could always stretch it 'just enough' to make the tub length match (just no overhang).
As far as cutting the NOS tub, why not. You've stored it for 20 years why let someone else get the benefit of the 'cool factor' you have into it. It makes a great story. How many of us have stored a new tub for 20 years and then cut it in half and stretched it???? I think nobody.
