I'm worried now!
I always threadlock screws into metal and I Z42'd all the screws into my TFR501 as I was building it. I had to get the top apart (to re-tension the belts, they were a bit tight) and it came apart fine but I haven't dared tackle the underneath yet. I've heard that heat is good when trying to undo stubborn screws, so I'll have a hairdryer on standby when I replace my screws woith some decent ones
As for the body being too low at the back, I thought this too, but once I fitted the undertray and the velcro strips they supply to hold the body on, the body was pulled out slightly at the back which brought the rear body down onto the rear mount. I was thinking I'd have to cut the body down at the rear too, but it all turns out good in the end.
I'm going to order some of those ti-ni shock shafts tomorrow (the Yok ones), I didn't make a very good job of building my shocks anyway so they'll come apart and get rebuilt properly with ti-ni shafts. I feel a set of B4 springs coming on as well.
