diff to drive shaft bolts boys,do i just buy em from tvr dealer or get some stainless steel ones from my local man.the heads are allen bolt type and though not in bad nick i think i will replace em while im there.also while on topic i was planning on putting in new propshaft bolts,the ones on the car i would say are near new but is it good practice to replace em once they have been removed?
I agree with Tanguero, don't use stainless steel and also only use bolts with a long shank so that the torque is taken on a plain section

' Where can I use A2-70 Stainless Steel bolts ?
A2-70 can be safely used to hold car body panels and bumpers in place.
Wing bolts, hinge bolts, handles, locks, light fittings etc.
A2-70 can be safely used on non-mechanically loaded engine components where a clamping action is required.
Manifold attachment, ancilliary attachment, pipe clamps, flanges etc.
A2-70 can also be used for securing access panels, cover plates and accessory items to the vehicle.
Where should I NOT use A2-70 Stainless Steel bolts ?
A2-70 should not be used in heavily loaded mechanical or structural areas.
Areas of direct loading on the suspension.
Areas of direct loading on the steering column and linkages.
Active engine componets (con-rods, crank shaft, clutch & power off-takes)
Active gearbox and power-train components.
A general rule of thumb is that it's OK to replace 8.8 and lower rated nuts and bolts.
Any nut or bolt stamped with a 10:9 or 12:9 should be replaced with an identically rated (or higher) component AND NOT an A2-70 component.'
