drive shaft
Hope you guys can help
What I’m building is an off-road street legal with big wheels /tyres now to get the gearing right + reverse I was planning is to run through VW beetle
transaxle how to connect the two?
1/ straight shaft using sprocket adapter –tube –wielded to centre of an old friction plate. Tube fixed at engine end just slid over gear box shaft.
Down side is now room for alignment error and vibration or
2/ run with 2 UJs but how to fasten to gear box
Any one have any suggestions

What gearbox are you using?
AH, just realised the topic is in BEC so igonore the above, I am a pinto man. Dont know anything about BEC's, YET! Project 2......
Plus, are Beetle Transaxles any good? Had heard they were a bit floppy and flimsy. Not my opinion, just a memory

As weight kills BEC's and the moving mass of offroad wheels and tyres coupled to a seperate gearbox I would be surprised if you even got up a
decent hill.
You need to reduce as much weight in the driveline so chain driven sprocket has to be the way to go. For reverse you could try and get clever using a
landrover transfer box diff running as a jackshaft which would reduce reverse ratio by 2:1 + running as a jackshaft you adapt the gearing easily.
I think you would be better with a front wheel drive car engine/box across the rear wheels.

Chain would be to short and get hot so that’s out
Front wheel drive car engine/box across the rear, drive shafts would be too short to get decent wheel travel so no good
