I'm planning the rear end of my buggy. I will be running a 1500 single port and plan to have 70 profile tyres. I have a 1200 trans. Should I be looking to get a 1500/1600 trans?

What are the pros and cons of each?

If you search on here I think it was Dave who posted up a spreadsheet that work workout speed/gearing/tyre size.

the 1200 box will give you better acceleration but the rev difference at 60 cruising is only a couple of hundred rpm. 70 profile depends on the width old school 205/70 X 15 gives you 26 1/4 inch diameter.

1200 and 1300 boxes are the same ratios. I'm running a 1600 tp  with a 1200 box and its fine, accelerates well and your nerve will run out before you get it flat out. Just build it!

I'll stick with what I've got then. Will probably be a G-70 tyre on a 8" smoothie.

Have you got a body for it?

No. Want to build up the chassis first. Can't afford one to be honest!

Mathew..... Do every possible thing you can before fitting a body.... I didn`t and golly have I suffered. It`s no joke growing old 

Rob recons he could get one more shell out of the Classic/Signature Manx mould, if not a Manx 2 tub with a Classic bonnet and dash could be the perfect combination.

Did you not have a shell from the aborted monocoque?

Yeah I sold what was left of the failed mono project.

Last time I spoke with Rob he said he had made a new buck for a Manx 1 with a Manx 2 rear seat. Was going to wait for that to be ready. With a Manx 1 bonnet and dash. I will put textured paint on the dash to try and replicate the ABS look.

He seems to be selling the Manx as the Classic Buggy now; Manx tub with Sidewinder bonnet. I'm sure he still has the Manx bonnet moulds though. The early dash looks much better but is harder to get wiper mech to speedo clearance, it is possible though, I've done it twice.

Yeah I'm sure he'll still have it. Still think it's a shame the office ones aren't made in the U.K.

I know, there was a bit of horse trading went on at one stage but Portugal it is I'm afraid. God knows how brexit will affect things too!

Rob might take over then!

I don't know about that, well I do, or did, but can't possibly say here. Still, if it wasn't for a certain Frenchman poking his nose in all may still have been rosie for UK Manxes.
