We need to model it in CAD and have it 3D printed... then paint as you see fit...

Looks like they're about 7 inches tall. The lower box is about 2 1/2 inches square by 3 1/2 tall. The dome is 1 1/2 diameter and 2 1/2 tall. I bought one and will see what I can do about printing it for 3-D replication.

Been on vacay, and trying to get the garage organized, so haven't got much done yet on the Spyder. I did cut out the grill and slats before my wife and I left.

Next week is Pagoda Hillclimb and I'll be working a corner Saturday and doing some family stuff Sunday, but after that I'll be posting more regularly.

In search of a transaxle person nearby so I can get the R&P and 4th gear changed out. If anyone knows anyone they can recommend based in MD or South Central PA please advise.

Geno's Aircooled Competition will do a trans for you. He's a VW drag racer, old school Elizabeth PA, basically Pittsburgh. That's all I know of. I can change bearings and synchros and gears, oh my. But I don't have the tools to set up a R and P swap.

Thanks, Danny. I'll check with Geno but it's kind of a haul.

Continuing progress: Jack points tested (good!), horn pockets, gauges, transaxle and a crack fix on the hood.

Making the rear clamshell inner swiss cheese piece now out of aluminum. It's not as hard as I'd thought.

What tire sizes are you thinking of running?

I ask because I have a 3.44/0.93 transaxle and I had been running a 195/60/15 in the rear. I recently switched to a Vrederstein 185/70/15 moving from the 24.2" tall wheel to a 25.2" tall wheel. This added about 3 mph to my gearing which isn't much, but it makes a difference cruising down the highway. A 3.44/0.89 would heve been better choice because I could have stayed with the more common 195/60/15 and had the better highway gears. The 0.82 4th would be too tall. I tried el-cheapo Nankang 165/80/15 tires ( 24.6" tall) and they seem to run nicely, but the side wall profile is taller than I like and I didn't like them as well. It's a small difference, but it's one of those things that if I could do it over I would change.

Probably gonna run tall-skinnies: Vred 165/80s. But the decision is not yet made. I have two 205/60s and 2 185/65s plus a set of 165/80s to try. I'd love to try 185/70s on the back but had not seen that size available....

I have the same gearing and the Nankang (or similar) Beetle tires on my Subaru-powered MG replica. I'm just about at 70 mph at 3000 and I think that's just right (I believe those tires are about 25.5 inches tall, not 24.6, fwiw). The car gets to 60 in a little over six seconds and I'm still in second gear when it happens. Third could get me to 100 if I wanted to be an idiot....

So I like the tires and the gear spacing and the power-to-weight ratio (13 lbs per hp, roughly, with the 137-horse EJ22). The power-to-weight in the Spyder with the 1914 should be under 12 pounds. I know a lot of Spyders have a lot more engine than that and that's fine; "more power to you," as it were. I'm looking for 60 mph in about 6 seconds flat at the top of second, which I think is just about right for these cars when in the hands of mortals.

No doubt the .89 4th gear would work well, and get you to about 75 mph at 3000 with the tall skinnies. Guys running lower profile tires would probably like the .89 better than the .93 but, as you say, we're down to fine details now and so personal preference is paramount.

Sorry, I meant 25.4" on the nankangs.

It's hard to tell by the pic, but did they do short axles or long? If you have short axles you can fit 5.5" wheels like these http://vintagespyders.com/product/vintage-190/. If you have long axles you can only get 4.5" wheels to fit properly, unless you move the offset. I have long axles so I am limited by the 4.5" wheels with the Vintage 190s which is why I went to the 185/70/15 tires on the rear. I am running the Nankangs on the front and the Vredersteins on the back. If I can get my speedometer corrected I'd prefer to go back to the 185/65/15 on the front.
