Yeah, probably not far off. These things always kinda evolve as you go along. Things change -usually when you find the bits you'd planned to use don't fit. When we tacked on the rear shock mounts it dropped the back end by a couple of inches, but we've been using an old pair of rear tyres to build on that were totally flat. Took them to a local tyre depot yesterday & they bunged in new valve cores for free & pumped 'em up to 30psi -which has lifted the back end back up again.
I was in Speedshack in West Drayton, London, this afternoon, buying wheels studs for Taz's trike, & the young lad in the queue next to me turned out to own a Pinto engined Pop, same year as mine. He's going to the Watford rod show on Monday, same as we are, so I think we'll be exchanging ideas. Can't wait till we can drive ours to it's first show.
